Delta - Game Emulator Reviews

by Srio00

Writing this so more people can see including the developers. The emulator is great, works with everything it says, it’s awesome we have a dedicated emulator for iOS now, but my big issues are related to the sound.

The sound quality is pretty bad, with frequent audio crackling/skipping/lagging (on an iPhone 14), and the emulator, given its DS compatibility, always has the microphone on, which means I am unable to be on call with someone through say, Discord, without disabling the sound of the game itself. This is very annoying as someone who plays games with friends and an audiophile.

Of course, if these issues don’t bother you, then it’s perfect! But these issues have been discussed many times on the application’s Discord server, Reddit, and even directly mentioning it on Twitter. It astounds me that there’s been no option for us to say, turn off the microphone function, or for there to be more focus on sound quality. Those are my two cents however - I applaud the customization and functionality, I just would like more attention on these things.

on the previous update everything worked fine, had no problems with apple tv connectivity or loading saves. this new update comes out and all my saves are incompatible (fair and understandable) but now every time i try to load any new saves i made after this new update the whole app crashes and renders that save unusable. (saving through the game and not Delta can fix this but it was annoying because it worked just fine before) also every time i would stream the game to my apple tv before this update, wether with controller or not would have absolutely 0 problems besides some latency. ever since this new update it’s been extremely laggy, (to the point where it’s unplayable not just a little bit of latency) and to top it off some my controller buttons will cease functioning when entering a game and i have to go back to the menu to re map it to find out it was mapped and just stopped working. to then have 0 issues remapping it, meaning the controller and connection to my device is perfectly stable. OTHER THAN THAT, top 5 apps on my phone n i absolutely love it. this alone tho makes most of my games unplayable for the time being, unless using the touch screen and phone screen. still possible but a little annoying since it all worked so well jus yesterday :(

When I started up Delta and loaded up a game I noticed that their was no sound for the game so I just thought I needed to refresh Delta and so I did but still no sound. So now I’m questioning if it’s just my phone so I restart my phone and I load up this app and load up a game and still no sound on the games. So now I decided to try another app game and guess what. There is sound for that, so now I’ve come to conclusion that Delta is having trouble with sound not just the games but on everything. What I haven’t done is delete and redownload Delta but even if I do and let’s say it “fixes” the issue. What if the sound goes away again? Do I really have to delete Delta and redownload again? I wouldn’t like doing that all the time. Please fix

I’m really enjoying Delta so far, but I’ve run into a problem. It’s very minor, but the audio is sometimes choppy and minor little glitches or discontinuous moments happen with the audio sometimes. I don’t know what causes this and maybe it’s just related to the power and processing of the device it’s on? It happens slightly less on my boyfriend’s iPad. I’m using a 7th generation iPad, so it’s obviously a bit older. I’m hoping this can maybe be fixed with an update, because it’s really my only big complaint. I suppose also, sometimes exact movement with an iPad stylus or Apple Pencil can be hard to register, but that’s not as much of a problem for me as the audio, and it seems to vary by game.

Overall, I really hope this issue can get fixed, audio glitching or slight choppiness really ruins the experience more than any other possible issue.

This is a really great app and its something that I've been waiting for apple to officially put an emulator on Delta store for YEARS and man has Delta delivered. Systems run really well and I barley notice any stuttering. While I only tested some games I'm worried for systems like the N64 control layout might be a bit awkward to use the other layouts are great for the most part. My biggest complaint about Delta is the lack of non Nintendo consoles. While why I understand that the Nintendo systems are some of the most popular, consoles like the Sega Genesis, Atari 2600 and PS1 are oddly left out. Since they announced that they will be adding more systems so they will most likely add some of these systems, as of right now as someone who plays non Nintendo systems more, it feels very limited. Again this is an amazing app and I can't wait for future updates

by Destroid Reaper

Let me get started by saying this is the most fun I’ve had in a LONG time, playing retro games, playing Rom Hacks (Radical Red), and just enjoying my time.

The only thing holding me back from a 5⭐️ is the fact that I cannot have multiple instances of the same game without save states. For an example, I have my main Radical Red save file on a rom. I can’t seem to have a second version of that rom, regardless of what it’s named, where it’s downloaded, or when it’s downloaded. When I try to load up a completely separate file for the rom, it just boots up the original. The only way around it is convoluted and unsafe for the data because of the chance of overwriting the file, that being the export/import save option.

All in all I love this emulator, and the only thing that could make it better is the option to have two versions of the same rom active at the same time, without the use of the export/import save functionality.

by Möbius76

this app is a extremely cool app that allows you access to a wide Variety of games that come with a convenience never before, but it doesn’t feel quite polished. Changing skins is a massive inconvenience that needs to be streamlined for the future. Furthermore the skins that come with Delta often feel distracting to the game. Some problems I have encountered with the emulator itself are few but the most noticeable one is for The n64. When emulating something like tloz mm, opaque textures such as the clock often have a white or black box behind them. I have not encountered a game that this issues makes unplayable, but still Anoying. Very happy that there is a emulator that you can finally get without side loading or having to paying money/adds(Very happy about that), but this app has not reached its full potential. Looking forward to the next update! -sounds kinda insane but would love to be able to play together online as a second controller with another phone

by Guitar_allstar

this app is awesome. Performant, tons of features, extras (cheats, save states, etc). But I have noticed some kinks. I have no doubt updates will come out for this app. But I have personally experienced poor lighting issues in Perfect Dark and Goldeneye both for the N64 core. Also my Bluetooth controller doesn’t work when my phone screen is off while this app is still running, my phone screen must be on for my controller to work via AirPlay to my smart TV. Also Landscape mode for Nintendo DS on my particular iPhone doesn't look good at all! It’s two tiny screens stacked on top of each other like Portrait mode when they should be two screens side by side. I understand it’s an issue of aspect ratio but maybe there’s way.

by Mnavarro20

I have to say, for a first time app of emulating games on the iOS, I’m very please and impressed. I have yet to try out any other of the emulators included in Delta however, I’m please to say the DS emulator runs great.

My main and pretty much only critique is that the screens for the DS, even on an iPhone 15 Pro Max, are pretty small. It detracts from the immersion a bit, and they have no included black skin, though pink is one of my favorite colors, it’s very harsh on the eyes if you’re not outside. Of course that’s subjective but i would really like the ability to magnify the screens a bit more, or the ability to remove the skins. I’ve played phantom hourglass a bit and have had no issues with performance or stuttering, it runs great.

by Modren83

This is a very clean, simple-to use emulation frontend that does exactly what most people need it to do. However, I do hope the developers add more options for advanced users. In particular, I'd really love to see some scaling and aspect ratio options. NES and SNES games are too skinny, which other emulators have long since fixed; making them 4:3 by default or having that as an option would be greatly appreciated. Integer scaling would also be nice to have, especially since a lot of the systems go right up to the edge of the bottom screen in horizontal mode and the white iOS bar can cover things up. And I'd also love to see some shader options if it's possible. Generally though, if you just want to play some ROMs, this is a great solution for now.

I’m a user of the “this app” App, and I love Delta, except for 1 thing, the sound emulation for the Game Boy Advance. For some reason, the audio for Game Boy Advance games on the “this app” App sounds horrible, I say this because I played “Wario Land 4” on Delta and it made an annoying noise, there wasn’t any music or sound effects, just this annoying noise that made me wish I was deaf. The “this app” App is a great app to emulate retro games, but there’s no excuse for the sound emulation issues with Game Boy Advance games on “this app”, especially since the other games that aren’t Game Boy Advance games sound just fine in “this app”, and Nintendo Switch Online has Game Boy Advance games too, but they sound fine on there. So there’s no excuse for the bad sound emulation for Game Boy Advance games on “this app”. Don’t get me wrong, I love “this app”, but it would be better if the people who made “this app” would fix the bad Game Boy Advance sound emulation on “this app”.

by RedTomi89

The emulator itself is really good, but there are a few issues I’ve noticed. For one, when I tested out Conker’s Bad Fur Day, the texturing was all wrong. Game Boy and Game Boy Color games aren’t in their proper aspect ratio, and the colors on GBC titles look kinda muted. Kid Icarus ran slower than it should, and (at least on my IPhone XR) when you play a DS game with a controller, part of the screen is cut off in Landscape Orientation (which, when playing a text-heavy game like Ace Attorney or an RPG, is really annoying), forcing me to either play at a weird angle in screen lock mode with my Kishi, or play in portrait mode using a completely different controller. This last issue could easily be fixed with an option to keep things in a 16:9 window in Landscape as opposed to the Ultrawide window of the XR. Don’t let this dissuade you overall, but these things are important to keep in mind when you use this. As for things to add in the future, I would like to see microphone support added to Famicom & Famicom Disk System games that supported it, such as Zelda no Densetsu - The Hyrule Fantasy, and Takeshi’s Challenge.

by DinovDoxy4608

I would love an option to make the ds screen to be vertical when playing horizontal, or at least one that works since when I click on the “arrange screen’s horizontally” it doesn’t really do much from what I’ve seen. I would also like an option to customize the controller skins on Delta by colour at least instead of only being able to download a skin online, and maybe an option to position where inputs are when playing horizontal tho idt that would work with having a skin on so probably just have a warning screen to tell the player that. And finally idk if this is a problem about Delta or discord, but when I try streaming the emulator on a discord call the audio cuts out completely even when I don’t have silent mode on. That’s about it for my issues, I really like Delta and i can’t wait for more emulators for other retro consoles

by Matroem

I am really glad to have picked up Delta. The process to set everything up feels easy once you understand how everything works. The menu navigation and features are just enough and the controller support is INSANELY appreciated. I do have one issue that bugs me. When ever I screen share the game (specifically DS) it only displays the top screen on the tv I use screen share on and I can’t find a way to have it display both the top and bottom screens but I don’t think this issue is too mandatory. Overall I will for sure be using this emulator on trips!

by AJ Campy

this app has been great, I’ve had a blast playing through older Gameboy games. That being said, there are two issues for me: I really would like the ability to customize the spacing of the on screen buttons in app instead of having to rely on a skin. I’ve got big hands and my thumbs specifically start to get sore when playing because of the angle I’m holding them at to be able to use the D-Pad and the A/B buttons. Second, there seems to be a sound glitch that I’ve only noticed on GBA Pokémon games (Ruby/Sapphire/Emerald, LeafGreen/FireRed) where every 15-20 seconds or so, the music skips. It didn’t bother me too much at first but now it’s all I hear which is a bummer since the nostalgia of the music is a big part of why I enjoy playing these games again. It’s not an issue through RetroArch using any of the available cores so it seems to be a this app-specific problem.
Overall though, it’s been fantastic and I am so grateful to the developer and co for bringing this to life.

I’ve been trying to get this emulator working on my phone since 2019. Now it’s on the AppStore without revokes! However there is some problems I have with the emulator itself. When connected to a tv via a dongle, it duplicates the screen instead of the game showing up on the tv and the controls on the phone screen, some romhacks don’t work properly or even work at all, I can’t load save files, and the DS emulator requires external files. I would like a turbografix16/pc engine emulator along with the sega emulators I’ve seen on other versions of Delta.

by J~Dilla

When I saw that purple this app symbol in the AppStore again, I thought it was too good to be true. I had the predecessor [GBA4ios]when i was in HS. So of course I downloaded this version. I had some ROMs from my previous attempts at other emulators, but this blew my mind. this app emulator runs smoothly, is aesthetically pleasing, and is quite easy to navigate. It also runs in an optional fast forward mode that can honestly be too fast at times, no complaints here though. Also, integration of cheats and other mods should be used with discretion, because they might damper your experience with the game. However, that fault isn’t to be left with the emulator, that’s all on you. Lastly, be sure to save your data often (in game & on emulator), because it’s easy to forget that you’re not playing a game that is already on Delta Store on its own & auto saving constantly, you’re on your mobile device. Therefore you need to save data yourself, to ensure no loss of gameplay. Otherwise, this emulator can & will change how you spend your free time. It is absolutely the best thing that I’ve come across!

//1. I've been using the this app emulator on my device, and I must say, it's an absolute joy. The interface is clean and uncluttered, which makes navigating through settings and games an effortless experience. //2. There are no annoying ads to disrupt the gaming session, and the smooth operation enhances every aspect of gameplay. The convenience of the emulator is top-notch, thanks to its intuitive controls and compatibility with a wide range of game formats. It brings back all those nostalgic moments flawlessly, running classics without a hitch. //3. However, there's one feature that would make this app even better — expanded cloud sync options. Currently, it supports Google Drive and Dropbox, which works well but integrating iCloud sync would be a game-changer for iOS users. This addition would streamline game data management across all Apple devices, making it much more accessible and secure. //4. In conclusion, this app is a superb emulator that offers a premium nostalgic gaming experience. If iCloud support were added, it would undoubtedly be the perfect package. Highly recommended for anyone looking to relive their favorite gaming memories on the go!

An Emulator is a piece of software that is able to run old games by simulating the consoles those games were made for. Emulators are completely legal. The games they run are the ROM files obtained by dumping the contents of physical cartridges or discs. Doing this is also completely legal. What’s illegal is downloading ROMs off the internet. That’s piracy, and is why this app does not include them of a way to get them. You must provide ROMs yourself. However you go about that is your prerogative.

this app itself is an extremely powerful emulation suite that runs games as good as if not better than in some cases official hardware. Tons of customization of tools, very user friendly, works great with a Bluetooth controller if you don’t want to put up with touch controls, and is surprisingly easy on the battery.

GBA4iOS was something I used WAAAAY back in the day and I’m super happy to see it get a true successor project that managed to get on Delta Store officially.

by Bivrip Bonez

I’ve been using Delta for a few weeks now, and I’m super impressed. I only have two gripes with Delta . It occasionally crashes when switching games, but I can’t emphasize enough how minor a flaw this is. My other gripe is that when using my X-Box controller with Delta (which is almost a necessity for me when playing N64 games), there is no way to access the menu for load/save states or to switch games. Other than that, Delta works very well, is extremely user friendly, and is just all around fabulous for enjoying the great games of yesteryear. I look forward to GameCube support (which is in Beta, according to the developers). I would wish for more consoles to be emulated on Delta , but I fear I would max out the storage on my phone with ROMs.

In short, thank you to the developers for Delta, and thanks to Apple for allowing it on Delta Store.

by Dre JA

I’m happy apple has allowed emulation. It’s refreshing to not have to jump through hoops to support Delta. 5 Stars no doubt.

It’s great that there’s controller support but here’s a suggestion from a touch screen gamer. Maybe, in addition to the classic button layouts, you could work out some way to have the button placement customizable. So as to not be reaching to the top left and right of the screen for hitting the “L&R” buttons. Maybe a uniform shape language that allows a 6 or more button layout where our thumbs would naturally be. I’m no dev so I’m not sure of the complexity for an option like this but it would definitely be a nice addition in my opinion. A way to also blend the games from just being emulated to feeling more like a native touchscreen game.

Anyway. I appreciate you being here this app. Looking forward to whatever updates comes next.

My town was hit with a powerful tornado over a week ago, and we have been without power, internet, air conditioner, and utilities. I’ve been spending every day with my husband and his family cleaning up the damage, and at night, sitting in the dark before falling asleep, I played a GBC Nuzlocke challenge using this app. It has been a huge comfort to play through the games of my childhood again to take my mind off the stress and fear of the situation. I played GBA4IOS years ago, and enjoyed it greatly. When Apple released an update that made it difficult to use Delta and removed it from Delta Store, I was very disappointed and actually didn’t own an apple iPhone for years afterwards out of protest, and only bought one used when I needed to, so I’m glad to see they are now back up on Delta Store and able to be enjoyed.

Thank you again this app team for everything you do. This is such a sleek and comfortable, reliable, and easy to use app to play custom games, and it’s amazing it can support both GBA and GBC games. I can’t wait to see future updates which may allow for trading and battle!

by Anonymous2361975

While I already emulated before but this really got me into emulation and Retro gaming because my all of previous emulators lagged very badly and might not even run on my iPad (5th gen) the only other one I might recommend is dolphin but it’s for only two consoles and isn’t really retro gaming and it really doesn’t give the same feel, while there are occasions where this app won’t read certain ROMs that work on other you can always simply go for a different rom in the infinite ocean of the internet. there is also a problem where most DSI games do not read no matter what while I would like to have that fixed this experience is more than amazing for me and there aren’t many games on the DSI that I used to play so it doesn’t need to be fixed I’m happy enough right now. Thank you for all your hard work I really appreciate it

by Jajdlcjanabn

It’s still so surreal to see this app on Delta Store. I started using GBA4iOS and nds4ios about a decade ago, bought multiple Buildstore memberships on iEmulators for myself and a few friends, played iNDS and this app when they were first made available, and have been doing my weekly refreshes to use this app through the AltStore.

After all these years and all these different methods of playing, I felt a strange sense of satisfaction when downloading this app from Delta Store. It felt like the proper “conclusion” to a journey across multiple sites and methods of acquisition. Here’s hoping that this app has found a proper home on Delta Store and continues to entertain users for years to come.

Mr. Testut, thank you so much for providing entertainment so many people over the years by allowing us to play some of our favorite childhood games even when we no longer had the hardware to do so. For the countless hours of entertainment your apps have given me over the past 9 years, thank you.

by MaskMan1YT

I love Delta, I’ve basically replaced every mobile game on my phone with Delta, though there’s a few things that would be awsome to add in a future update. I hope they will add more emulators from other companies consoles (Like Sega Genesis, Saturn, and CD and also PS1) Also I wish there could be controller presets because Nintendo controllers and Xbox controllers have different layouts and I have to switch the buttons every time I switch. I wish I could have my save states be apart of the Sync because with my NES games I have to use save states because a majority of them don’t have a save system. Also I wish you could keep buttons if you don’t have enough buttons to map every button on the controller (I use a backbone controller and it only has 2 menu buttons while you need 3 for the menu, start, and select) also side note that you can use the joystick buttons which could’ve been used as menu buttons. And lastly I wish you could make your own controller skins in app though with an option to still import skins,

2014 was a year for emulators on iOS. We had GBA4iOS and iNDS especially. Just a couple from what would be so many emulators later on. The Digital Markets Act finally let this app release on Delta Store recently. This is a victory on every freaking level that basically means Apple’s iron cage is softening up. We need to keep this momentum from legislatures against Apple’s monopoly. This is genuinely the case where fighting the “security” guidelines means we get to have more fun.

this app’s just a Nintendo emulator. Imagine if PPSSPP finally released officially to Delta Store? God of War on iOS for everyone?

I’m playing DKC 1 and 2 right now on this app, and I don’t have to worry about stupid revokes every few hours after an install just to enjoy the games I played years ago. This is a victory for all of us. For anyone who wasn’t around so early on when this was the expectation around downloading this kind of app - be grateful to never experience an annoying popup about a certificate from random places in the world isn’t the end of your fun and save states for weeks/months.

by Someone567123

As a new iOS user, I'm glad that you can now use emulators officially without having to sideload, and I think that's awesome! There's not a whole ton of variety though, since at the moment, only Nintendo consoles all the way up to DS (excluding GameCube) are available to use. I was really hoping to be able to emulate Sega Genesis/Megadrive games right off the bat, but as I looked into it, it's still in beta development! I'd love to opt into the beta features, but I'm assuming that's a Patreon exclusive. I hope you guys can add more customization options too! Personally, controller skins are neat, but I'd love it if there was the ability to use filters and such, like an old CRT filter that blends in the pixels and smoothens things out a bit so that the dithering in certain games looks the way it was meant to be, like the Sonic 1 waterfall! Playing games in pixel-perfect integer scaling (so there isn't any weird pixel simmering on the screen) would be great for people who just like even pixels. As far as I know, there isn't a way to change the aspect ratio either. Some games look nicer when they're displayed in 4:3 instead of 8:7, which is the native resolution for both NES and SNES.

by NishiPlays

The latest update was amazing and fixed the AirPlay issue! But.. is there a way you can make it when airplaying on a Smart Keyboard it doesn’t think it’s a controller. I would love to mount my iPad and use the stylus.

Also another option, when airplaying gameboy color games. I would love to see my phone screen while airplaying so I can look where I’m moving while playing vs it only shows my buttons and not the screen. I use discord to screen share when I airplay it to my computer so it’s difficult to play my games and share the screen while playing since it doesn’t show me my screen as well. If those updates can be pushed out Delta would be PHENOMENAL. It already has so many great things but it could be better!

Thank you for making Delta! I appreciate the hard work you put into it!!

by Gabereviewss

I hardly ever review apps but wow, this app Emulator has really blown me away. I’m about 45 minutes into a fresh play through of Pokémon Emerald and so far I have to say I’m very impressed. This is an amazing emulator that does its job exceptionally well. The user experience is great and simple to use. There are no ads or annoying pop-ups distracting you from the game. The haptic feedback on button presses was not something I expected but really made playing the game FEEL better. You can even cloud sync your games and save states between your devices via Google Drive or Drop Box, meaning you can play your game on the go on your iPhone and pick up right where you left off when you get home on an iPad!

I will be recommending Delta to pretty much everyone who wants to play their old childhood favorites on their phone. Would love to see other consoles supported in the future like the PS1 or Sega Genesis!!

by ZTLaidlaw

Having access to Gameboy games on an iPhone is great enough, but the added bonus of SNES and N64 support is on a completely different level. Having all of my favorite childhood games in my pocket is insane! Here’s to hoping even more platforms (GameCube, Wii, etc.) are supported in the future.

My only critique is that the on-device files folder is a mess (this app > Database > Games). The loaded games and save files are just strings of numbers that reveal nothing about the games with which they pertain. It would be nice to have the game names inserted into the files so that we can tell which file belongs to which title. Right now, it’s just a wall of digits.

Overall, really awesome work! Thanks for bringing this project to iPhone. I’m so glad Apple finally gave in. Keep it up!

by Arky Heartless

After years and years of playing emulated games and emulators on PCs and various devices, this game emulator in a form of this app Game Emulator has finally hit iOS devices without the use of jailbreaking or sideloading.

Although Nintendo has a HUGE problem with game emulators for years, we still have other means of playing their IPs (aka intellectual properties) on other consoles/devices rather than purchasing their games/consoles or repurchasing their games on certain platforms.

Lets face it. The past consoles from the 70s until the mid 2010s are now being eBay’d or Amazon’d, not TEMU’d whereas most of the games from back in the day are spread across emulator websites, bootleg game consoles, etc where big name gaming companies like Nintendo are rendered powerless to try to zap every single one them to reciprocate every last dollar in damages.

Game emulation isn’t going anywhere, no matter how many game collections that’s been released on game consoles or remakes of any kind. Get acclimated. It’s here to stay if not, permanently.

So again, developers of this app Game Emulator, thank you for allowing us to relive every bit of our childhood memories through Delta. Hopefully you’ll bring more past consoles to Delta soon.

RATING: 5/5

I’ve had iPhones since the 3gs, and this is the first time I felt compelled to write a review for an app. This thing is perfect. It runs games perfectly. It saves games perfectly. It has the capacity to play games from multiple systems (and maybe more with updates?). And it works flawlessly with your files folder to get ROM files downloaded immediately ready to play. I was a little annoyed that I had to go an do the research to figure out how and where to get the right files, and you do have to do a little more digging to play DS games, but it shouldn’t take you more than a half hour. And once you’re done, everything just works. If you were a gamer in the 90s and 00s, the best thing you can do is download Delta and get started. All you’ll be missing is the button clicks :/

by Eevee Potato 555

I've only used a couple of mobile emulators before, most of them either have confusing layouts, are nearly impossible to put in games, or have horrible graphics. I'm really happy to say this isn't the case with this app!! After you figure out which files you need to boot up DS games it's extremely easy to put in the games you want! The graphics are AMAZING as well, I'm able to see all of the pixels without them blending into each other. It also has really good customization with being able to choose the cover art for the games you want to play and being able to have custom skins for the different types of consoles! My only real complaint is that some of the DS games speed up is a little slow, but other than that I would highly recommend!

by Ilove Spotify So Much

This is amazing. I finally get to play all the retro games I ever wanted. One thing I would like is the ability to maybe upscale the resolution I know the phone can definitely run it so if it’s possible, please try to implement it or at least in some consoles like the NES. The only reason why I want this feature is to see more clearly and just a better gaming experience in general, please and thank you.

Edit: for all the people giving it bad reviews please note that this is amazing. You just have to know how to use it. If you have issues like no audio or crashing it’s not the emulator. It’s actually the game you have downloaded. Trust me happened to me before not all games you download work immediately somewhere just hacked and supposed to annoy you.

TLDR: it’s not the emulator it’s the games you download.

This ain’t my first rodeo with iOS emulators. Before Apple allowed them onto Delta Store, I used an app called AltStore that you’d use your Mac to install outside apps onto your phone. One of these apps was this app - an all-in-one Nintendo-centric emulation app.

Delta is the first (never mind that one bootleg everyone talked about…) and possibly the best emulator app you will see on Delta Store. Seven supported game systems, meaning seven huge game libraries you now have the ability to jump into on your phone. The interface is easy to understand, and doesn’t waste your time. Absolutely no advertisements on Delta - even when it’s on Delta Store!

Organization and customizability is what I like about this app. You have the ability to set game covers, change controller layouts, skins, and even sync your game saves and files to your Google Drive for multiple devices! That is SOOO good.

There’s some things i wish to improve. First, the “auto-orientation disabled” feature for WarioWare: Twisted doesn’t really work. At all. I still have to turn on Rotation Lock in Control Center. Second: iPad support. I know Delta was definitely not designed around it but… hey, it could be pretty nice!

Overall, it’s a good emulator. Good performance, and gets the job more than done. I’ve been here since GBA4iOS, and I’m really happy to see how far we’ve come. This is great stuff, Riley.

by RigoRod_

I never leave reviews on any app because they are all pretty average. However Delta had coerced me to let people who are thinking about downloading Delta know how awesome it is! I’m a retro game collector, mainly Pokemon and have dabbled the world of emulation before on my desktop/laptop but this takes it to another level. I can play Generations 1-5 on this little app. Flawlessly and better than ever on the iPhone 15 Pro Max’s beautiful screen. They have a save state feature and the game changing fast forward feature!!! It’s game changing especially if you want to do speed runs, nuzlockes etc. I haven’t experimented with accessory controllers like the Backbone but from what I’ve read online it works flawlessly! Download Delta and reminisce on your childhood times! I’m a physical media guy and even though I own a lot of the Gen 4-9 games physically I’ve been opting to game on my phone a lot more since this was released for iOS.

Its all about preservation. Ive hoarded Nintendos content for the last 20 years. With my original save files slowly dying with the batteries in the cartridges. Wish I could retrieve the ones that still worked to this app. I Have followed Delta since the original and appreciate how its grown. Its possibly the best app thats been created so far. The attention to detail, as well as the versatility. Its a love song to retro consoles and our childhoods. A map that takes you back to things lost in time. The fact that it doesnt attempt to capitalize or cheapen the experience is icing on the cake. I wish all developers had the same mission values. I wonder if adobe will attempt to sue apple for Delta store logo. Since they've trademarked the letter A and all triangles 😂 I deleted long ago when found PDF expert to have less in your face advertising and better viewing customization for textbooks back when I was still in school.

I’m having a blast playing so many different things in what’s looking to become an all-in-one kind of emulator for different consoles and handhelds. I greatly appreciate how easy it was to get everything running as well. The only thing I’d truly love to see realized is a way to save controller profiles. For the most part, they’re all perfect, but the N64 having such a weird controller layout means that one controller setup may not work for all games. Mega Man 64 is wildly different in control to something like Mortal Kombat Mythologies, and each time I want to play something different, I have to completely reconfigure controls. This obviously isn’t a make or break deal because the option of changing is always a thing. Just a nice QoL feature that would be great to see!

I have been using this app emulator for the better part of 10 years now. Back in the day, we had to go through safari or special means to download Delta and games available to us. Now, in 2024, I am happy to see this is accessible very easily for us.

This is by FAR the best app I have found to play games for years to come. All you have to do is find the right file to download and BOOM - you're in unova, or sinnoh, or johto or even kanto.

Because of this game, I am able to relive my childhood while exploring new challenges in these games. I never imagine apple would take this emulator on, but I am happy to see they have and I am exploring my childhood day by day. I have grown up with pokemon for over 17 years and my other consoles arent as easily accessible due to being put up from moving, so being able to replay them while traveling or on breaks at lunch or just in my own personal time - i DEFINITELY recommend!!

I am blown away by having my old Game Boy Color, Advance, and N64 games literally at my fingertips. Today I played a round of Super Smash Brothers on my TV for the first time in literally 30 years thanks to Delta, AirPlay and my Xbox One Bluetooth controller. It’s incredible—super polished, accessible, and

I hope Delta continues to support new features to sand off the rough edges of emulation, like the ability to tweak joystick sensitivity or move virtual buttons on the screen. Flying games like Rogue Squadron are borderline impossible, but I’m not sure if that’s input lag or me being spoiled by 30 years of game development improvements. But man, these are minor quibbles. What a ride.

I was a bit skeptical when downloading this emulator, I had zero expectations. After downloading, it was quite easy to find a site to download game roms. I downloaded one of my favorites for the N64 which is Zelda: Ocarina of time. The game and emulator ran very smooth! Sound as well! One problem I didn’t like was trying to play without a controller, I quickly learned after looking on the this app app that you CAN connect a controller! I decided to connect my Xbox Series X controller. The last step is changing the controls to your liking, but once that’s all done then you should be all set! I can’t speak for other games and other console emulators you can download on Delta. However, for what I’ve experienced, I LOVE!

When I say I have been waiting for a good emulator to hit the apple App Store that couldn’t be more of an understatement. I have waited YEARS for something like this to come out and after trying it out for the past hour I can confidently say that Delta does everything I need and want and MORE. Seamless interface and customization for games and controller skins and it runs flawlessly and is VERY SIMPLE TO USE. If you are having any difficulties getting it to run the way you want it to, a little digging around the internet and Reddit forums will set you straight in no time. So happy and excited to finally have this seamlessly integrated into my iPhone and I couldn’t be happier about the user experience

I play retro games on every other platform available. I can tell, Delta has had some time and love put into it. I didn’t know what to expect on this platform, but Delta makes me expect more polish when it comes to gaming (Emulation) on apple products. Delta is well done. Changing skins is super easy. Loading roms is hassle free. Cover art is hit and miss for me. Could be a naming issue. But the built in save states and fast forward make up for it. I was able to pair an external controller and start playing immediately. No button mapping needed. Apparently Delta has been around for a while before Delta store. I am glad apple has lifted some restrictions now.

If you have been wanting to play your emulated games on iOS without side-loading or hacks this is Delta you have been waiting for. It has worked well for all the games I have played on it and the syncing data with Google Drive between devices is such a great feature.

I really hope they make an iPad version of Delta. Then we can utilize a larger screen with the buttons on either side of the game. Or use it in the full screen mode with a wireless controller and use the most of an iPad display. I think that would make Delta even more amazing for traveling with your game library.

This is perhaps the best emulator you can get for these systems. It runs the games quite accurately. One of the best features is the use of “skins” which allow you to customize not only the look but also the layout of the buttons. I also love the “hold buttons” feature, which is useful for sprinting in some platformers and driving forward in racing games.

The two bugs I found:
•Plays a popping sound in GBC games, but only if using earbuds. This sound cannot be detected by screen recorders - the only way to record it is to hold a microphone next to an earbud.
•DS games suddenly decrease in performance after a certain amount of time has passed. This does not appear to simply be a hardware limitation because they run just fine at first.

Despite the bugs, it’s still an amazing multi-emu, and it works flawlessly for NES, SNES, and GBA. I’m glad this exists so I can just carry my phone around instead of having to carry both a game console and and a box of cartridges and my phone.

this app has been the best mobile emulator out there for years, and Delta Store was really lacking Delta. The struggles of getting this app through 3rd parties was a short-lasting pain, but its finally here in a fully legal way and I’m so excited for it, I can’t wait to be able to play through the classics and not have to worry about reinstating Delta weekly on my device or the risks of losing progress. Delta has really good UI, and it’s very customizable. I’m sure this app will only improve, 5 stars

by AidenBak9

I have used this app for the past few years and in my opinion it is the MOST refined emulator on Delta Store/Marketplace. The one main reason I love Delta is that I am able to link my progress across many devices and redownload all my save data. Delta is also 100% free with no paywall, no hard to find settings, and no sneaky in app purchases. It is also one of the simplest emulator apps out there, just get your game, import it and boom your playing! In the past few days people have been shoving emulator apps left and right into Delta Store. Yes, I tested all of them so far and this app is the only app out there that is a legitimate free app and not a ripoff.

by Robwiredusa

Just a month ago no one could have imagined that this app would be downloadable directly from Delta store. Like a freakin Christmas in the Spring miracle its here and its incredible because its not a new app, its only new to normies who wouldn’t know how to get Delta through non-traditional means. Emulation, per se, isn’t wrong, regardless of what Nintendo would have you believe.

Since this app has been refined and has been working well for many years its battle-tested and ready. If you like what you see and want to support the developer just do a little research to find his Discord and other offerings!

Thanks Riley for making a dream come true.

I’ve been using this app for years now, and it is a fantastic app. Riley Testut is extremely talented, and I am so glad his hard work (both in development and activism for App Store changes) will now get the praise it deserves. The added quality of life features in this app make playing your old games better than on the original console, and I’m excited to see how Delta will improve even more with a vastly expanded user base now that it is on Delta Store.

For those that don’t know, Riley has been campaigning to get emulators allowed on Delta Store for years, and he is a major reason they’re allowed today. Enjoy!

by Carlos_bm

I've supported Riley's emulators since the early GBA4IOS days and I’ve gotta say, past me would have never believed that one of Riley's apps would ever officially release on Delta Store. It honestly feels like a fever dream 😅. Anyway, on the emulator itself; nothing else comes close to it on iOS. The interface is nice and clean and the games run perfectly. No ads, no data collection, just you and your games. The widget & haptic touch integration is something I really appreciate, as well as the customization options with controller skins. If you’re looking for a premier emulator for iOS, look no further.
Congrats on the launch, Riley! 🎉

The release of Delta will be put into the history books. It’s significant based on the fact that Apple seems to be loosening their controlling grip on your phone. Delta has only be available through an exhausting process but now you can just get it in two clicks.

I’ve used Delta for years prior to its official release and it’s always been amazing. I’m glad that it’s easier to obtain now. If you’ve ever owned a hand held console in the past, I highly recommend trying Delta out, it will allow you to relieve old memories.

What we’re living in today is a watershed moment in gaming. Millions of people can now play some of the best games ever created the way they were meant to be played. I anticipate hundreds of hours of enjoyment from Delta, and if you have kids of your own who you want to gift some of the best moments of many people’s childhoods to, I recommend you get Delta as well. I promise that you will not regret it. My only regret is that it took this long for us to even be able to find an app like this one on Delta Store.

by Tom Lock

I am so happy to be able to write this review. this app is my favorite emulator, and I have been using it for years now, and I have nothing but positive thoughts towards it and its developer. The interface is clean and readable, controller support is wide, the syncing (and versioning for synching!) has never let me down or lost my files. As I said, I am so so happy to be able to write this review today, I love Delta and appreciate the absolute heck out of this developer, I'm excited for what we have now, and excited for what they bring to us in the future

by LinkSurvivor1

I’ve tried the NES, GBC, GBA, and DS emulation and they all work flawlessly. My iPhone 15 Pro Max stays cool the entire time, and battery life is barely effected if at all.

This works way better than the former web app work around, and I can’t wait to see what other emulation cores are added.

One piece of feedback, the touch screen calibration on the DS doesn’t perfectly match up with where I tap - I have to tap slightly below where I actually want to select. Hopefully this can get patched in a future software update.

by EstebanD92

The emulation looks incredible! The only issue is I am not getting any sound for anything. I’ve tried turning silent mode on and off, vibration on and off, restart iPhone, install and reinstall. I am on iPhone 15 Pro, not sure if it is an issue with this model. Either way, I hope this gets fixed, but wanting to leave a positive review for how great the presentation is at the moment!

Update!
I found out what was causing no sound.
Under iPhone settings, accessibility, sound recognition, this needs to be off!

by Noah978

this app is the all-in-one emulator designed with Apple users in mind. It focuses on polish, simplicity, and most of all: user experience.

You’ll find other emulators like RetroArch or Provenance that have more consoles and more features. But this app will be the only one who’s experience is as smooth and Apple-esque.

I’ve used this app since its day one, even before its day one! And it’s good to finally see it up in a spot where everyone can use it. Cheers!

by DanRuizPixel

I’m using this for mainly DS titles, and it’s fantastic honestly. Gotta get used to not having tactile buttons you can physically feel, and having to look down at the controls to make sure you’re pressing the right button at times, but like I said that’s just something you gotta get used to.

I think the only real complaint I have (a nitpick really) is to add graphics settings, I wanna see the crisp polygons that the DS can really offer and not be bound to a low resolution, especially when running on much better hardware like a modern iPhone. Other than that I’m having a blast playing games I never got the chance to as a kid.

by UPDATE_#46

The emulation is great with a sleek UI and even showing you the box art of the ROMS you choose to insert into the application. However, I’ve been playing The Legend of Zelda Link’s Awakening and have notice that sometimes the audio will be slightly behind the actual gameplay. For example, I swing my sword and the “shingggg” comes slightly after. This is not a big issue, but it is still one that should be addressed in future updates of this application. Nevertheless this is still the best gameboy emulation for IOS by far, with its easy installation, and how easy it is to get playing. I would definitely recommend!

First of all apple deciding what is classified as retro is over stepping as a whole console gaming is now retro besides current and last gen of consoles witch there has only been three. Ps5 and Xbox whatever series and the switch, besides that these other consoles are classified as retro to the community. Can’t wait to see GameCube be added hopefully soon as it is a retro console…that being said overall I am grateful I no longer need to jail break my products to be able to play these games, I have ran into crashing issues when cheats were activated not sure if there is some errors occurring but overall 10/10

Edit for DS games I’m having issues with the blow feature the games offered not sure if it’s me or something else

by Amcbargelmaojdjd

this emulator is so easy to use and it has so many features that make playing from an emulator more enjoyable. adding roms is a simple process, you don't have to go through any additional "set up" steps to add/play. and the ability to "save state" without saving in game is amazing. i love the fast forward button and adding cheats is super easy so i got to actually use cheats for the first time!! the only thing i could possibly want more from Delta is if you were to add 3ds emulation!!

i have not experienced any issues with the on screen controller or Delta crashing like other emulators i've tried. Delta truly makes emulating a breeze- and i've played games on gbc, gba and ds in this emulator and all work just as well!!

but PLEASE PLEASE PLEASE consider adding 3ds emulation to Delta ! i'd love to play some of my fav 3ds games on an emulator that runs as smoothly as this one
