Delta is the best Game Boy emulator for most iPhone and iPad owners because it is easy to install from the App Store, supports Game Boy, Game Boy Color, Game Boy Advance and several other Nintendo systems, and includes practical features such as save states, fast-forwarding and controller support. Choose SameBoy instead if accurate original Game Boy and Game Boy Color behavior matters most; choose RetroArch for maximum customization and Provenance for a broad multi-console library.
There is one important iOS 17 qualification: an App Store listing can change its minimum operating-system requirement. Before installing, open the current listing and check Requires iOS for your exact iPhone or iPad. The rankings below describe each app’s capabilities, not a guarantee that its newest version runs on every device still using iOS 17.
Which Game Boy emulator should you choose on iOS 17?
Use this quick guide before comparing the details:
- Delta: the easiest all-round choice for Game Boy, GBC, GBA and other Nintendo consoles.
- SameBoy: the specialist choice for original Game Boy, Game Boy Color and Super Game Boy accuracy.
- RetroArch: the most configurable option for experienced users with large, mixed-system libraries.
- Provenance: a polished alternative when you want Nintendo, Sega, Sony and Atari systems in one library.
- Manic EMU: a feature-heavy option with multiple cores, broad handheld support and an integrated ROM patcher.
- Folium: a paid choice for readers who want Game Boy alongside DS, 3DS and other Nintendo handhelds.
“Best” here means best for a particular use case. Game Boy (the original monochrome system), Game Boy Color, Super Game Boy and Game Boy Advance are related but distinct platforms, so a good GBA choice is not automatically the best way to reproduce original Game Boy behavior.
How do the six iOS emulators compare?
| Emulator | Best for | GB | GBC | GBA | App Store and price signal | Main drawback |
|---|---|---|---|---|---|---|
| Delta | Most players and beginners | Yes | Yes | Yes | U.S. App Store; free download with in-app purchases shown | Narrower system range and less specialization than rivals |
| SameBoy | GB/GBC accuracy and unusual peripherals | Yes | Yes | No | U.S. App Store; free with in-app purchases shown | Does not target GBA or multi-console libraries |
| RetroArch | Power users and many platforms | Through cores | Through cores | Through cores | App Store; free | Complex interface and iOS core restrictions |
| Provenance | Broad, polished multi-console libraries | Yes | Yes | Yes | Free App Store access described by the project | More breadth than a Game Boy-only player needs |
| Manic EMU | Feature-heavy all-in-one use | Yes | Yes | Yes-related support is listed | App Store listing; current price not reliably stated in available listing information | Newer project and more core-related choices to understand |
| Folium | Game Boy plus DS/3DS and other handhelds | Yes | Yes | Yes | U.S. App Store result showed $2.99 | Paid, and demanding systems may be slow on older hardware |
System support in this table means the app advertises a compatible core or emulator. It does not promise that every game, BIOS-dependent feature, peripheral or performance level works on an iOS 17 device.
Is Delta the best overall Game Boy emulator for iOS?
For most people, yes. Delta has a comparatively approachable library interface, official U.S. App Store distribution and support for Game Boy, Game Boy Color, Game Boy Advance, NES, SNES, Nintendo 64 and Nintendo DS. Its listing is at the official Delta App Store page.
What Delta does well
- Save states and normal in-game battery saves are both available.
- Fast-forwarding, cheat codes, game artwork and external-controller support reduce friction during play.
- It can cover a Pokémon or Zelda library without requiring a second app for NES, SNES or DS titles.
- Optional online-compatible Nintendo DS multiplayer is advertised, although the exact experience depends on the game and network setup.
Where Delta falls short
Delta is not the most specialized choice for reproducing the original monochrome Game Boy’s timing, palettes or unusual hardware. Its supported-system list is also smaller than RetroArch, Provenance and Manic EMU. If you only play GB and GBC and care about hardware-specific behavior, SameBoy is a better fit.
How Delta is distributed
Availability varies by region. Delta’s official guide explains that the App Store and AltStore PAL are separate distribution paths and that location affects which one you see: Delta’s distribution guide. For a general audience, the official App Store edition is preferable because it avoids expiring developer certificates and unofficial download pages.
Delta’s iOS 17 check
Open the live App Store listing and read its Requires iOS line before installing. If the current release requires a newer iOS version, do not assume that an old IPA from an unverified site is safe or will work; update iOS when your hardware supports it, or select an emulator whose current listing supports your device.
Verdict: Start with Delta unless you have a specific accuracy, customization or multi-system requirement.
Is SameBoy the most accurate choice for Game Boy and Game Boy Color?
SameBoy is the strongest specialist option when your library is primarily original Game Boy, Game Boy Color or Super Game Boy. Its App Store description emphasizes accuracy-focused emulation and lists hardware-specific features that general-purpose frontends often omit: the official SameBoy App Store page.
Special features for original hardware
- Game Boy, Game Boy Color and Super Game Boy support.
- Game Boy Camera and Game Boy Printer emulation.
- Rumble and motion-control emulation for software that uses those capabilities.
- Shaders, fast-forward, rewind, slow motion, cheat codes and controller support.
- Save states with gesture-based quick save and load.
- The listing says there are no ads or tracking and mentions iCloud support for ROMs and saves in its update information.
SameBoy’s accuracy language is a project claim rather than an independent benchmark, but it is directly relevant to players who notice palette, timing and display differences. It is not the obvious option for GBA, SNES, N64 or DS.
How to import a game into SameBoy
SameBoy’s support instructions say to import a ROM file into the app, including by tapping a downloaded file in the device browser: SameBoy’s iOS support page. Use a game dump you are legally entitled to use; the app does not supply commercial games.
SameBoy’s iOS 17 and price qualifications
The U.S. listing shows a free download with in-app purchases, but the available listing information does not establish one universal all-inclusive price. Check the live listing for its minimum iOS version and current purchase details.
Verdict: Pick SameBoy when GB/GBC fidelity, Super Game Boy or Camera and Printer emulation matters more than a large console catalogue.
Is RetroArch worth using on an iPhone or iPad?
RetroArch is worth it for experienced users who want one frontend for many systems and are willing to learn cores, playlists and input settings. It is free, open source and ad-free, with Game Boy, Game Boy Color and Game Boy Advance support delivered through cores. The official listing is RetroArch on the App Store.
What makes RetroArch powerful
- One interface can cover Nintendo, Sega, Atari, PlayStation, PSP and many other platforms.
- Save states, netplay, cheats, shaders, fast-forward, rewind, custom overlays and button remapping are built in.
- RetroAchievements and game artwork can be integrated into a larger library.
- The SameBoy core is one documented route for Game Boy and Game Boy Color emulation; see the SameBoy core documentation.
Why RetroArch is harder on iOS
“RetroArch supports this system” does not mean every desktop core is present or usable in the iOS App Store build. iOS signing and platform rules affect core availability. RetroArch’s official iOS documentation warns that improperly signed or unavailable cores can cause loading errors. The official core catalogue is useful for orientation, but do not copy its desktop assumptions to an iPhone.
For a single Pokémon game, RetroArch’s setup overhead is unnecessary. For a carefully curated library with custom shaders, netplay or per-game input profiles, that overhead buys more control than Delta provides.
Verdict: Choose RetroArch for capability and customization, not for the quickest first launch.
Is Provenance a good Delta alternative?
Provenance is a strong alternative when Game Boy is one part of a much larger retro collection. The project lists Game Boy, Game Boy Color, Game Boy Advance, NES, SNES, N64, DS, 3DS, GameCube, PlayStation, PSP, Saturn, Dreamcast, Atari and additional systems. Its project page is the official Provenance repository.
Library and importing features
- Save states, cheats, fast-forwarding, custom controller skins, artwork, filters and RetroAchievements are documented.
- ROMs can be imported through Files, AirDrop, Safari downloads or WebDAV.
- The project describes itself as free and open source, with no required account, ads or tracking when sideloaded or built from source.
- The official FAQ describes App Store availability and free access; the Game Boy system page covers its GB support.
What to consider before choosing it
Provenance’s breadth is unnecessary if you want only Game Boy. It also spans workloads with very different demands: a GB title is light, while 3DS, GameCube and Dreamcast can be much more demanding. Treat system support as a starting point and judge performance on your specific iPhone or iPad.
Verdict: Use Provenance when you want a polished, broad library and do not mind having more systems than you currently play.
Is Manic EMU a good feature-heavy option?
Manic EMU targets users who want many Nintendo and non-Nintendo systems, multiple cores and modern convenience features. Its current App Store listing is the authoritative place to check availability, price and requirements: Manic EMU on the App Store.
Notable capabilities
- Game Boy and Game Boy Color support, with an option to switch between mGBA and VBA-M cores.
- GBA-related support, BIOS importing for multiple platforms and continuing iOS updates.
- Save-state improvements, fast-forward controls, RetroAchievements and an integrated ROM patcher.
- Controller configuration and AirPlay-related options are documented in the listing.
Why core choice matters
Having multiple cores can help when one implementation behaves better with a particular game, but it also creates another troubleshooting variable. If a patched game or peripheral behaves differently after a change, record which core and settings you used before migrating saves.
Manic EMU is newer and less established than Delta, RetroArch or Provenance. The available listing information does not provide a reliable current price or complete minimum-iOS table, so check both directly before installing on iOS 17.
Verdict: Consider Manic EMU when feature breadth and ROM patching outweigh the simplicity of a more established app.
Is Folium worth paying for if you mainly play Game Boy?
Folium makes sense when Game Boy is part of a larger Nintendo handheld setup. It supports Game Boy, Game Boy Color and Game Boy Advance alongside Nintendo DS, Nintendo DSi, Nintendo 3DS, New Nintendo 3DS, NES, SNES, Sega Genesis/Mega Drive, PlayStation 1 and ColecoVision. The U.S. App Store result showed a $2.99 price: the official Folium listing.
Hardware and convenience features
- Support is listed for Backbone One, Nintendo Switch, PlayStation and Xbox controllers.
- Save states, direct boot, game importing, artwork and multiple cores are documented.
- The listing explicitly says Folium does not provide games or system files.
Why it is not the default recommendation
If you want only Game Boy, free App Store options offer a lower-cost starting point. Folium’s more demanding systems may also run slowly on older devices, so an iOS 17 iPhone that handles GB perfectly may still struggle with 3DS or other heavier workloads. Check the listing’s current minimum iOS version and device notes before buying.
Verdict: Pay for Folium when DS/3DS and a broad Nintendo handheld library are central to your plan, not merely because it can launch a Game Boy ROM.
How do you choose between GB, GBC, SGB and GBA support?
Read the platform labels literally. Original Game Boy software can depend on monochrome palettes, timing and hardware quirks; Game Boy Color adds color hardware; Super Game Boy reproduces Game Boy software through an SNES accessory; Game Boy Advance is a separate, more powerful handheld. Delta, Provenance, Manic EMU and Folium cover GBA as well as GB/GBC, while SameBoy concentrates on GB, GBC and SGB.
| Your priority | Best starting point | Reason |
|---|---|---|
| Pokémon, Zelda and other GB/GBC/GBA games with minimal setup | Delta | Simple library workflow and broad Nintendo support |
| Original GB/GBC timing, palettes or Camera/Printer titles | SameBoy | Accuracy-focused specialist features |
| One customizable frontend for many consoles | RetroArch | Cores, shaders, remapping and netplay |
| Nintendo plus Sega, Sony and Atari in one library | Provenance | Broad system coverage and flexible importing |
| GBA plus patching and multiple core choices | Manic EMU | Feature-heavy workflow |
| GB plus DS or 3DS | Folium | Paid handheld-focused catalogue |
How do you install and configure an emulator safely?
The safest general workflow uses the official App Store listing and your own legally obtained game dumps. Do not use random IPA mirrors, enterprise certificates, “modded” apps or websites that offer copyrighted ROMs.
- Check compatibility first. Open the live listing, verify Requires iOS, and confirm that your iPhone or iPad model is supported. Availability can vary by country.
- Install from the official source. Use the App Store page linked in this article. If an app offers another official regional route, read its documentation rather than downloading a signed copy from a third party.
- Open the app and review permissions. Grant only the access needed for Files, notifications or cloud features you intend to use.
- Import a legal ROM. In Files, AirDrop, Safari or the emulator’s documented importer, select a game dump you are legally entitled to use. SameBoy specifically documents importing by tapping a downloaded file in the browser.
- Select the system or core. Most library-based apps identify GB, GBC or GBA automatically. RetroArch and multi-core apps may require you to choose a core.
- Set controls before a long session. Pair a Bluetooth or wired controller, remap buttons if needed, and test the portrait, landscape and touchscreen layouts. Compatibility is app- and game-dependent; controller support does not guarantee that every peripheral behaves identically to original hardware.
- Create both kinds of save. Make a normal in-game save, then test a save state. Native saves are the safer long-term record; a state can fail after a core change, corrupted file or app migration.
- Test suspend and backup. Lock the device, resume the app, test fast-forward and audio, then back up important save files before updating or moving to another emulator.
What should you know about controllers and display options?
All five leading options named in the listings or documentation advertise some form of external-controller support, but the details differ. Delta, SameBoy, RetroArch, Folium and Manic EMU can work with at least some Bluetooth or wired gamepads, including families such as Xbox, PlayStation, Nintendo Switch and MFi devices. Pair the controller in iOS Settings, then map buttons inside the emulator.
- Bluetooth: convenient and widely supported, but latency and battery life vary by controller.
- Wired: can reduce latency and charging concerns when the adapter and iOS device support it.
- Remapping: important for games that use shoulder buttons or unusual layouts; RetroArch is especially configurable.
- Touch controls: useful for quick play, but custom skins and per-game layouts make long sessions more comfortable.
- Orientation and external displays: options differ by app and version. Test landscape mode, iPad multitasking and AirPlay before relying on them.
What are the main iOS 17 limitations?
The biggest limitation is uncertainty around version requirements. App Store presence does not prove that the newest build supports iOS 17, and an older compatible build may not be offered automatically. Check the listing’s current requirement and avoid assuming that a downloaded IPA will install, remain signed or preserve saves.
App Store editions can also differ from desktop or sideloaded editions. RetroArch’s iOS code-signing rules can limit cores; broad claims about desktop compatibility should not be treated as an iPhone guarantee. Similarly, a multi-system app may launch a light GB game smoothly while struggling with 3DS, GameCube or Dreamcast on an older device.
Finally, App Store and sideloaded distributions have different maintenance costs. The App Store generally avoids certificate expiration and is the sensible route for most readers. Sideloading can expose different builds or cores, but it adds signing, installation and update work.
Are emulators and ROMs legal to use?
An emulator is software; a commercial game ROM or BIOS/system file is a separate matter. Use game images and system files that you are legally entitled to possess and use under the laws that apply where you live. The apps listed here do not give permission to download copyrighted games, and Folium explicitly says it does not provide games or system files.
Do not follow links to unauthorized ROM repositories, BIOS collections, certificate-signing services or unofficial IPA stores. Besides legal risk, those downloads can contain modified files, intrusive profiles or malware. For fan translations and ROM hacks, use the patch creator’s legitimate distribution and follow the emulator’s documented patching workflow; RetroArch advertises soft patching and Manic EMU advertises an integrated ROM patcher, but compatibility varies by format and core.
What is the final recommendation?
Install Delta first if you want the least complicated path to Game Boy, GBC and GBA on an iPhone or iPad. Move to SameBoy for original GB/GBC accuracy and unusual peripherals, RetroArch for deep customization, Provenance for a broad multi-console collection, Manic EMU for feature breadth and patching, or Folium when DS/3DS justify its paid App Store price. In every case, verify the live minimum iOS requirement before committing to an iOS 17 device.
Frequently Asked Questions
Can I transfer my Game Boy saves between these iOS emulators?
Sometimes, but it is not automatic. Battery-save files and save-state files use different formats, and a state created by one core may fail in another; export a normal in-game save and keep a backup before experimenting with migration.
Do I need a BIOS file for Game Boy emulation on iPhone?
Requirements depend on the core and system. The SameBoy Libretro documentation says its reverse-engineered Game Boy and Game Boy Color boot ROMs are built into that core, but that does not establish the same behavior for every platform or core in a multi-system app.
Why does an emulator appear in the App Store but refuse to install on iOS 17?
The developer may have raised the minimum operating-system requirement after the app was listed. Check the listing’s current Requires iOS field and your device model; an older compatible version may not be available, and an unofficial IPA is not a dependable workaround.
Can I play multiplayer Game Boy games with a controller?
Controller support and multiplayer support are separate features. Pairing a second controller does not guarantee link-cable emulation, while some apps advertise network or Nintendo DS multiplayer only for specific systems and games.
