Delta is the best emulator for most iPhone and iPad owners. It is the easiest way to play legally usable NES, SNES, Game Boy, Game Boy Advance, Nintendo 64, and Nintendo DS game files. Choose RetroArch for the widest configurable multi-system setup, PPSSPP for PSP, Gamma for the simplest PlayStation 1 experience, Folium for Nintendo 3DS, and ArcadeMania for MAME arcade games. For a single app covering the most platforms, compare Manic EMU and Provenance.
This guide covers official App Store options for U.S. users as checked on August 10, 2026. Availability, prices, minimum operating-system requirements, and supported features can change. None of these apps normally includes commercial games: you must provide compatible game files and, for some systems, BIOS or other system files.

Quick answer: which iPhone emulator should you install?
| Emulator | Best for | Systems | U.S. App Store listing | Setup | Main limitation |
|---|---|---|---|---|---|
| Delta | Most beginners and Nintendo retro systems | NES, SNES, Game Boy, GBC, GBA, N64, DS | iPhone and iPad; iOS/iPadOS 14+ | Easy | Not a general PSP, PlayStation, arcade, Dreamcast, or DOS emulator |
| RetroArch | Power users and maximum breadth | Arcade, Atari, Commodore, DOS, Nintendo, PlayStation, PSP, Sega, and many more | iPhone and iPad; iOS/iPadOS 12+ | Advanced | Cores, BIOS files, playlists, and iOS signing make setup less intuitive |
| PPSSPP | PSP | PlayStation Portable | iPhone and iPad; iOS/iPadOS 13+ | Easy to moderate | Dedicated to PSP; App Store build does not use JIT |
| Gamma | Simple PlayStation 1 emulation | PS1 | iPhone and iPad; iOS/iPadOS 15+ | Easy | Free tier contains advertising |
| Folium | Nintendo 3DS | 3DS, New 3DS, DS/DSi, GBA, GB, NES, Genesis, SNES, PS1, ColecoVision | iPhone and iPad; iOS/iPadOS 16+; paid | Moderate to advanced | 3DS performance and compatibility vary significantly by device and game |
| Manic EMU | Broad all-in-one App Store library | 3DS, DS, PSP, PS1, Dreamcast, Saturn, MAME, DOS, Nintendo, Sega, Atari, and more | iPhone and iPad; iOS/iPadOS 15+ | Moderate | Subscription or lifetime purchase; broad listing does not guarantee equal maturity |
| Provenance | Open-source Apple ecosystem and Apple TV | Dozens of Atari, Sega, Nintendo, Sony, arcade, computer, and other systems | iPhone, iPad, Mac, and tvOS; iOS/iPadOS 16+ | Moderate | Demanding systems need newer hardware; some features are in development |
| ArcadeMania | MAME and arcade games | MAME, vintage computers, and electronic games | iPhone and iPad; iOS/iPadOS 13.4+ | Moderate | ROM sets must match the supported MAME version |
Best one-app choice: choose Delta for ease or Manic EMU/RetroArch for breadth. Best two-app combination: Delta plus PPSSPP, or Delta plus RetroArch. On iPad, Delta or Provenance makes a good library app, with PPSSPP or Gamma added for dedicated systems.

What an emulator does—and what it does not include
An emulator is software that reproduces the behavior of an older console or computer. It provides the virtual hardware, graphics, audio, controls, save systems, and other functions needed to run compatible software on iOS or iPadOS.
The emulator normally does not provide commercial games. You supply a game file, which may be called a ROM, ISO, CSO, CHD, or another format depending on the original system. Delta says it requires users to import their own ROM files, PPSSPP requires users to provide their own PSP game files, and ArcadeMania does not include arcade ROMs. See Delta’s importing guide and PPSSPP’s official game-file guidance.
Some consoles also need a BIOS or other system firmware. A BIOS is not the same thing as a game. Requirements vary by emulator, core, and system: some platforms work without one, while others need a correctly named firmware file in the correct folder.

Delta: the best overall emulator for most beginners
Install Delta if you mainly want Nintendo games and a polished, low-friction experience. It supports NES, SNES, Game Boy, Game Boy Color, Game Boy Advance, Nintendo 64, and Nintendo DS on iPhone and iPad. Its U.S. App Store listing requires iOS/iPadOS 14 or later and offers save states, fast-forward, cheats, custom controller skins, external-controller support, keyboard input, artwork, synchronization, and iPad features.
Delta is a particularly good fit for Pokémon, Zelda, Mario, Kirby, Metroid, and other Nintendo handheld and 8-, 16-, or 64-bit libraries. Its normal workflow is closer to a modern game library than to a technical emulator frontend.
How to import a game into Delta
- Obtain a game file that you are legally permitted to use.
- Open Delta.
- Tap the + button in the top-right corner.
- Select the file in the iOS document picker.
- Wait for the game to appear in the library, then tap it to launch.
Delta’s documented formats include .nes for NES; .smc, .sfc, and .fig for SNES; .gb, .gbc, and .gba for Game Boy systems; .ds and .nds for Nintendo DS; and .n64 and .z64 for Nintendo 64. The guide also lists .gen, .bin, .md, and .smd Genesis extensions. Because the documented format page may lag behind current releases, check Delta’s current FAQ if a file fails to import.
Delta’s strongest features
- Save states, fast-forward, cheats, screenshots, and customizable touch-controller skins.
- Support for PlayStation, Xbox, MFi, Switch, Joy-Con, and keyboard controls, according to the App Store listing.
- Documented Google Drive and Dropbox synchronization for games, saves, save states, cheats, skins, and mappings.
- Local multiplayer for compatible NES, SNES, and N64 games, plus online-compatible Nintendo DS play through community WFC servers, as described by the listing.
- Dedicated iPad support, including fullscreen play, iPad controller skins, Stage Manager and Split View support, Handoff-related features, and DS improvements recorded in its version history.
The U.S. listing recorded version history through Delta 1.7.3s on November 11, 2025; version information is volatile, so check the live listing before publication or installation.
Where Delta stops
Delta is not the answer for PSP, PS1, Dreamcast, Saturn, arcade, or DOS games. It may be the right first app, but readers with a mixed library should add a specialist emulator or choose RetroArch, Provenance, or Manic EMU instead.
RetroArch: the best choice for power users
RetroArch is the broadest and most configurable option, but it is also the least beginner-friendly. It is a frontend for libretro cores, not one single console emulator. Each core is an emulator component for a particular system or family of systems.
The U.S. App Store listing advertises support for arcade, Atari, Commodore, DOS, Game Boy, GBA, NES, SNES, Nintendo 64, PlayStation, PSP, Saturn, Sega CD, 3DO, Neo Geo, PC Engine, Nintendo DS, and many other platforms. It also lists save states, netplay, RetroAchievements, cheats, overlays, shaders, fast-forward, rewind, artwork, and extensive controller options. RetroArch is free, ad-free, open source, and requires iOS/iPadOS 12 or later, according to the listing.
The important iOS limitation
On desktop, RetroArch users may be accustomed to downloading and updating cores inside the application. The iOS documentation explains that iOS cores are signed executables and cannot ordinarily be added or updated after installation. The App Store build therefore includes the available iOS cores in its signed application. Do not promise unlimited desktop-style core downloads on an iPhone or iPad.
Basic RetroArch setup on iPhone or iPad
- Install RetroArch from the App Store and launch it once.
- Open the Files app and choose Browse → On My iPhone or On My iPad → RetroArch.
- Create a ROM folder, or copy files into an existing RetroArch subfolder.
- In RetroArch, choose Load Content and select a game.
- Choose the appropriate installed core if RetroArch asks you to select one.
- For playlists, use the content-import workflow after the necessary databases and core information are available.
Libretro’s content-import documentation describes database updates and playlist scanning. A game can still fail to appear when its filename does not match the database, the required core is unavailable on iOS, or a BIOS file is missing.
RetroArch is the better choice when you care about per-core settings, shaders, latency options, remapping, netplay, or RetroAchievements. Delta is the better choice when you want to add a game, tap it, and start playing without learning the difference between content, cores, databases, playlists, and BIOS files.

The lighting is vibrant yet eye-friendly. The built-in 600mAh battery provides up to 6 hours of battery life in brightness mode — enough for a full day of gaming
Dedicated emulators: PPSSPP, Gamma, Folium, and ArcadeMania
PPSSPP: best for PSP
PPSSPP is the clear specialist recommendation for PlayStation Portable games. It has an official iPhone and iPad App Store release requiring iOS/iPadOS 13 or later. The free app supports ISO, CSO, and CHD game files; PPSSPP Gold is listed at $3.99 in the U.S. App Store.
PPSSPP’s official iOS documentation says modern iOS devices can generally reach full speed without JIT, although JIT can reduce battery consumption. The App Store build does not use the same JIT path available to sideloaded builds. PPSSPP also does not run PS1 games simply because some PS1 titles were playable on PSP through Sony’s own software; use Gamma or another PS1-capable emulator for those.
Recommended Free Tools
Transfer PSP games over Wi-Fi
PPSSPP 1.20 and later documents a convenient Wi-Fi upload method:
- Put the iPhone or iPad and computer on the same Wi-Fi network.
- Open PPSSPP and go to the Games tab.
- Navigate to the folder where the game should be stored.
- Tap the folder-with-up-arrow Upload icon.
- Open the displayed URL on the computer.
- Upload the ISO, CSO, or CHD file, then return to PPSSPP and browse to it.
On a Mac, you can instead connect the device, open it in Finder, choose the Files tab, select PPSSPP, and drag the game files into the app. Windows users can use Apple Devices for file transfer. See PPSSPP’s iOS support documentation for current details.
A physical controller is strongly preferable for PSP games. Touch controls work for menus and slower games but are less comfortable for action games with shoulder buttons and analog movement.
Gamma: best simple PS1 emulator
Gamma is the easiest dedicated PlayStation 1 option for many users. Its App Store description lists CUE/BIN, CHD, PBP, ISO, MDS, and compressed-archive support, along with cover artwork, custom controller skins, enhanced rendering, widescreen options, analog controls, cheats, screen mirroring, multiplayer, per-game memory cards, save-state synchronization, and screenshots.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsGamma requires iOS/iPadOS 15 or later. The free tier contains advertising, while Gamma Pro is listed at $4.99 for ad removal. It is a good choice when you want PS1 only and prefer a library interface over RetroArch’s core-based configuration.
When importing disc-based games, keep related files together. A CUE/BIN release may require both the cue sheet and its matching track files. Multidisc games may need a particular arrangement, and memory-card files should be backed up separately from save states.
Gamma’s App Store description uses claims such as best compatibility and most stable. Those are developer marketing claims, not independent benchmark results. Choose Gamma for simplicity, not because those claims establish universal compatibility.
Folium: the most relevant 3DS specialist
Choose Folium when Nintendo 3DS is the deciding factor. It is a paid App Store app listed at $2.99 in the U.S. and requires iOS/iPadOS 16 or later. Its listing advertises Nintendo 3DS and New Nintendo 3DS, DS/DSi, GBA, Game Boy, NES, Genesis, SNES, PlayStation 1, and ColecoVision support.
Folium does not provide games or system files. Its update history documents 3DS-specific work, iPhone 16 and newer iPad support, save-state validation, cheat handling, Nintendo Wi-Fi Connection support with custom servers, and updates to its Cytrus-based 3DS component.
Folium is not a guarantee that every 3DS game will work on any iPhone. Performance, crashes, controls, battery use, and screen layouts can vary substantially by title and device. App Store reviews report such problems, but user reviews are failure reports rather than controlled compatibility testing. Treat Folium as the most relevant specialist option for 3DS, not as a universal 3DS solution.
The iPad is generally the better form factor for DS and 3DS because its larger display gives the two screens more usable space. Even then, check the actual layout and stylus controls for the games you care about before building a large library.

- Cushioned and Durable Membrane: The X5 Lite is equipped with cushioned and durable membrane triggers and buttons. The cushioned feedback provides a comfortable experience while ensuring quieter operation
ArcadeMania: best dedicated MAME option
ArcadeMania is the most focused choice for arcade emulation. Its listing says it uses MAME 0.278 and supports more than 5,000 arcade games, as well as vintage computers and electronic games. It includes a native Metal renderer, custom shaders, HDR, save states, cheats, hardware-keyboard support, touch analog input, and touch light-gun input. It lists Xbox One, PlayStation 4, PlayStation 5, and Switch controller support, and requires iOS/iPadOS 13.4 or later.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
ArcadeMania does not include ROM files. More importantly, MAME ROMs are version-sensitive. A ROM set prepared for another MAME version can produce missing-file errors or fail to boot. The advertised number of supported games does not mean that a random ROM archive will work with MAME 0.278.
Broad all-in-one alternatives: Manic EMU and Provenance
Manic EMU: broad coverage in one App Store app
Manic EMU is the most convenient breadth-first alternative for readers who want one library instead of several specialist apps. Its U.S. App Store listing advertises Nintendo 3DS, N64, DS, GBA, GBC, GB, NES, SNES, Virtual Boy, PokeMini, PS1, PSP, Dreamcast, Saturn, MAME, DOOM, MS-DOS, Java/J2ME, Sega Master System, Game Gear, SG-1000, Genesis, 32X, Sega CD, Atari 2600/5200/7800/Jaguar/Lynx, and more.
Listed features include RetroAchievements, multiple save slots, fast-forward, cheats, filters, custom skins, iCloud synchronization, cloud imports, WebDAV/SMB, controllers, multiplayer, and AirPlay. The U.S. listing requires iOS/iPadOS 15 or later and shows $0.99 monthly, $4.99 annual, and $9.99 lifetime purchase options. Check the live listing before publishing or buying because pricing and purchase structures change.
The trade-off is transparency and maturity. A long supported-platform list is an App Store claim; it does not establish equal compatibility or identical polish across NES, 3DS, Dreamcast, Saturn, PSP, arcade, and DOS. Manic EMU is appealing if avoiding multiple apps matters more than choosing the most established specialist for each system.
Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Clear out junk files and repair common Windows errorsFree Scan →Provenance: best open-source Apple ecosystem alternative
Provenance is a strong choice for an organized multi-system library, especially if Apple TV support matters. It describes itself as an open-source multi-emulator frontend for iOS, iPadOS, macOS, and tvOS. Its documentation lists 38 or more supported systems spanning Atari, Sega, Nintendo, Sony, 3DO, Neo Geo, arcade, PlayStation, PSP, Dreamcast, Saturn, and other platforms.
The U.S. App Store listing requires iOS/iPadOS 16 or later, is listed at approximately 2.5 GB, and offers Provenance Plus at $3.99 monthly, $39.99 annually, or $99.99 lifetime. According to Provenance’s Plus information, core emulation features remain free while Plus adds convenience features such as iCloud synchronization and priority or early-access features.
Provenance is a good fit for readers who value open-source development, library presentation, cross-device Apple support, optional iCloud synchronization, and Apple TV. Its own performance guidance classifies NES, Game Boy, SNES, and Genesis as easy; PlayStation and N64 as moderate; and Dreamcast and PSP as demanding. It recommends iPhone 11 or newer for demanding systems and an M1 iPad or newer for demanding iPad use. Those are the project’s recommendations, not independent benchmarks.
Do not treat PS2 as a normal App Store feature. Provenance’s supported-system documentation marks PlayStation 2 as in development and requiring JIT. The same caution applies to any modern platform listed in promotional material without game-by-game compatibility evidence.
App Store availability, price, and jailbreak requirements
For the U.S. storefront checked for this guide, all eight recommended apps have official iPhone and iPad listings, with the minimum versions shown in the comparison table. Availability can vary by country, storefront, developer release, and app version. Search the exact app name and developer, and use the official project or App Store link rather than an unofficial IPA.
Apple’s current App Review Guidelines explicitly permit retro game console and PC emulator apps, subject to Apple’s privacy, content, software, and legal requirements. Apple’s policy change in April–May 2024 is why reputable emulators can now appear in the App Store without a jailbreak. RetroArch’s documentation records its App Store availability beginning May 15, 2024.
No jailbreak is required for the App Store builds discussed here. Sideloading is mainly relevant to advanced users who want builds or capabilities restricted by Apple’s App Store environment, especially JIT. It adds signing, certificate, update, trust, and security complications. Do not install random configuration profiles or so-called JIT enablers from unknown websites.

Prices and purchase structures are snapshots, not permanent guarantees. Gamma’s advertising, Provenance’s optional Plus tier, and Manic EMU’s subscription or lifetime options are particularly important to check before choosing an app.
Which iPhone or iPad is powerful enough?
Separate installation compatibility from emulation performance. An iPhone may meet an app’s minimum iOS version and install successfully while still struggling with demanding Dreamcast, PSP, Saturn, or 3DS games.

- Older compatible iPhones and iPads: Stay with NES, SNES, Game Boy, GBA, Genesis, and many straightforward PS1 or N64 games. Lower rendering resolution and simpler effects if necessary.
- Modern iPhones: PSP, Dreamcast, and some 3DS workloads become more realistic, but performance remains title-specific. A newer processor does not guarantee that every game or emulator core is compatible.
- Modern iPads: The larger screen is better for DS and 3DS dual-screen layouts, external controllers, multitasking, and longer sessions.
- M-series iPads: These are the strongest iPad choices for demanding workloads when the emulator supports the relevant system properly. Provenance recommends M1-class iPads or newer for its demanding category.
Apple’s iPadOS 26 compatibility list begins with the iPad mini 5th generation, iPad 8th generation, iPad Air 3rd generation, and various iPad Pro models, alongside newer A-series and M-series iPads. That list only describes operating-system eligibility; it is not an emulator performance guarantee.
Leave room for game files, CD images, save states, artwork, shaders, and duplicate imports. The App Store currently lists RetroArch at approximately 683 MB, Manic EMU at approximately 650 MB, and Provenance at approximately 2.5 GB, but those are app sizes—not the storage needed for your library.
Do you need a controller?
Touch controls are adequate for turn-based games, RPGs, puzzle games, menus, and many Game Boy titles. A physical controller is strongly recommended for:
- Nintendo 64 games.
- PSP and PS1 games with analog movement.
- Arcade fighting games and shoot-’em-ups.
- 3D platformers and racing games.
- Light-gun games.
Delta documents support for PlayStation, Xbox, MFi, Switch, Joy-Con, and keyboard input. ArcadeMania lists Xbox One, PS4, PS5, and Switch controller support. PPSSPP and Provenance also list external-controller support. Exact button mapping and advanced features vary by app.
Pair the controller in Settings → Bluetooth before opening the emulator. Delta’s controller documentation says the controller must first appear in the device’s Bluetooth settings. After pairing, open the emulator’s controller or input settings and verify the face buttons, analog sticks, shoulder buttons, and menu shortcut.

Common file types
- ROM
- Usually cartridge-based game data, such as NES, SNES, or Game Boy files.
- ISO
- A raw optical-disc image, commonly used by PSP and some disc-based systems.
- CSO
- A compressed PSP ISO.
- CHD
- A compressed disc image supported by several emulators, including PPSSPP and some RetroArch setups.
- CUE/BIN
- A disc image arrangement consisting of a cue sheet and one or more track files. The cue file may need its companion files beside it.
- BIOS
- System firmware that some consoles or cores require. It is separate from the game.
- Core
- The individual emulator component loaded by a frontend such as RetroArch.
Universal setup checklist
- Update the iPhone or iPad and confirm it meets the emulator’s minimum OS version.
- Install the app from the official App Store listing.
- Pair a controller in Settings → Bluetooth if you plan to use one.
- Obtain compatible game files through a lawful source or a personal dump made in accordance with applicable law.
- Import one simple game first instead of moving an entire library at once.
- Make a normal in-game save and test a save state.
- Export or back up important saves before changing emulator versions, cores, game files, or apps.
Delta uses the + button and the iOS document picker. PPSSPP offers Wi-Fi upload through its Games tab in current releases. RetroArch uses the Files app and its Load Content workflow. Other frontends may provide cloud, WebDAV, SMB, or in-app import tools, but the exact labels can change between versions.
Normal saves versus save states
A normal in-game save is written by the game to its cartridge save area or memory card. A save state is a snapshot of the entire emulator session, including the game’s current machine state.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesUse both, but treat normal in-game saves as the primary backup. Save states can become invalid after an emulator update, core change, altered game file, or different BIOS. Cloud synchronization is useful, but it is not automatically a conflict-free backup. Export important saves before major changes.
Are iPhone emulators and ROMs legal?
The emulator application and the game file are separate legal questions. Apple allowing emulator apps in the App Store does not legalize downloading or distributing copyrighted games.
Commercial game files are generally copyrighted. Use homebrew, legally licensed material, or game dumps made in accordance with the law that applies to you. Do not assume that owning a physical cartridge automatically makes downloading a ROM legal everywhere, and do not assume that a personal backup exception applies in every country or to every circumvention method. This is general information, not individualized legal advice.
Nintendo’s official piracy FAQ identifies copying, downloading, and distributing unauthorized game products—including ROM-site copies—as piracy concerns. This guide does not link to unauthorized ROM repositories.

- Confirm the region, extension, and system match.
- Try another compatible core if using RetroArch.
- Disable shaders, texture enhancements, and high-resolution scaling.
- Turn off fast-forward and rewind.
- Restart the emulator and device.
- Create a new normal in-game save rather than relying on a stale save state.
- Check the emulator’s official documentation or issue tracker for the particular game.
Delta’s troubleshooting guide notes that damaged or altered files can cause freezes and startup failures. Some large ROM hacks may also need additional software and should not be assumed to work like standard releases.

The game runs slowly
Slow emulation may come from the device’s processor or memory, high internal rendering resolution, shader overhead, audio synchronization, thermal throttling, battery-saving mode, or the lack of JIT in an App Store build. Reduce enhancements first, close unnecessary background apps, keep the device cool, and test the game at its native or default resolution.
Provenance specifically recommends disabling smoothing and CRT filters, closing background apps, and following system-specific performance guidance. Do not interpret one slow game as proof that the entire emulator is unusable; demanding systems often have game-specific requirements.
The screen layout is wrong on an iPad
iPad support does not automatically mean an ideal DS or 3DS layout. Check for dual-screen sizing, portrait and landscape modes, touch-stylus mapping, controller overlays, external-display aspect ratios, and whether the Apple Pencil is recognized as the game’s stylus. A larger iPad generally offers more usable space, but some apps still require manual screen positioning or scaling.
The emulator says JIT is required
App Store builds generally cannot use the same JIT path as sideloaded builds. PPSSPP’s official documentation says modern iOS devices can generally run PSP emulation at full speed without JIT. Provenance documents PS2 as in development and JIT-dependent. JIT is not a universal switch that makes every modern-console emulator practical.
If you choose a sideloaded build, understand the signing, update, trust, and security implications. Avoid random JIT-enabler websites and configuration profiles.
An app disappeared from the App Store
- Check that the device is using the correct country storefront.
- Search the exact app name and developer.
- Visit the official emulator project’s website or documentation.
- Check whether the developer has released a replacement listing.
- Do not install an IPA from an unknown site simply because an App Store listing is unavailable.
Be especially suspicious of clones using misleading names, stolen screenshots, or unsupported claims about Switch, PS2, PS3, Xbox, or modern PC emulation. App Store availability and distribution rules can vary by storefront.

Privacy and trust checklist
App Store presence is a useful safety signal, but it is not a complete technical or privacy review. Before enabling cloud import, iCloud synchronization, WebDAV, SMB, or third-party storage:
- Open the app’s App Store Privacy section.
- Read the developer’s privacy policy.
- Check which services receive account, file, diagnostic, or usage data.
- Use only storage accounts you trust.
- Keep independent backups of saves and important files.
- Prefer official project links and verified developer names.
RetroArch and Provenance are open-source projects, but open-source status does not by itself guarantee that every configuration is private or secure. Review the specific app’s current disclosures.
Final recommendations by reader
- Install Delta if you want the easiest route to NES, SNES, Game Boy, GBA, N64, or DS games.
- Install PPSSPP if PSP is your priority. It is more focused and better suited to PSP than a general frontend.
- Choose Gamma if you want a simple PS1 library and do not mind advertising in the free tier.
- Choose RetroArch if you want maximum breadth, RetroAchievements, netplay, shaders, remapping, and per-core control—and are willing to learn its workflow.
- Choose Folium if you specifically want 3DS and accept paid software, system-file setup, and uneven game compatibility.
- Choose Manic EMU if one broad App Store library is more important than having the most mature specialist app for each platform.
- Choose Provenance if you value an open-source Apple library, iCloud options, Mac support, and Apple TV integration.
- Choose ArcadeMania if MAME arcade games, light-gun input, shaders, and arcade-focused controls are your priority.
For most people, start with Delta and add PPSSPP when you want PSP. For a technically minded user with a mixed library, RetroArch is the most flexible second choice. For a single broad library, compare Manic EMU and Provenance on price, platform maturity, cloud features, and Apple TV needs rather than choosing solely from the length of their supported-system lists.
Frequently Asked Questions
Can one iPhone emulator play every retro system?
Not reliably. RetroArch, Manic EMU, and Provenance advertise the broadest coverage, but systems use different cores, BIOS requirements, and hardware demands. Delta is easier but focuses primarily on Nintendo systems, while PPSSPP, Gamma, Folium, and ArcadeMania are stronger specialist choices for PSP, PS1, 3DS, and arcade games.

Sometimes. BIOS requirements depend on the console, emulator, core, and game. A BIOS is system firmware, not a game file. Use only system files you are legally permitted to possess, and consult the emulator’s official documentation for the required filename and folder.
Can Delta run PSP or PlayStation games?
No. Delta is primarily for NES, SNES, Game Boy, GBA, Nintendo 64, and Nintendo DS. Use PPSSPP for PSP and Gamma, RetroArch, or another PS1-capable emulator for PlayStation 1.
Is JIT necessary for PSP emulation on an iPhone?
PPSSPP’s official documentation says modern iOS devices can generally reach full speed without JIT, although JIT may improve battery efficiency. The App Store build does not use the same JIT path as sideloaded builds.
What is safer: an App Store emulator or a sideloaded IPA?
For most users, the official App Store build is the simpler and safer route because it avoids certificate and signing complications. Sideloading may provide advanced features such as JIT, but it introduces additional trust, update, and security decisions. Avoid unknown IPA download sites and configuration profiles.
The Bottom Line
Delta is the best starting point for most iPhone and iPad owners. Add PPSSPP for PSP, Gamma for simple PS1 emulation, Folium for 3DS, or ArcadeMania for MAME. Choose RetroArch, Manic EMU, or Provenance when a broad multi-system library matters more than the simplest setup. Whichever app you select, use legally usable game files, back up normal saves, and treat advertised system support as a starting point—not a guarantee that every game will work perfectly.
