SpatialEMU brings your own retro game library to iPhone and iPad. Organize a personal local collection, choose how each game is presented, and play with touch controls or supported physical game controllers. SUPPORTED SYSTEMS Play user-provided games for NES, SNES, Game Boy, Game Boy Color, Game Boy Advance, Nintendo DS, Mega Drive / Genesis, SEGA 32X, Master System, Game Gear, SG-1000, PlayStation, PSP, DOS, Neo Geo, CPS arcade systems, SEGA Model 2, SEGA Model 3, and supported MAME arcade hardware. Compatibility varies by title, file format, and required system files. LOAD LOCAL FILES OR USE YOUR OWN SERVER No server is required: open local games directly with the system document picker. FolioSpace Library is an optional, self-hosted personal library and is not part of the SpatialEMU client. It can run on a NAS or on a Docker-capable Mac, PC, or Linux host. Connect to your own server to browse, search, filter, and selectively download your catalog, save multiple server profiles, and synchronize supported battery saves and play records. PLAY YOUR WAY Use the app's virtual controls or supported Xbox, PlayStation, Nintendo, and other game controllers. Universal controller mapping supports global, per-system, and per-game profiles, button reassignment, axis inversion, dead zones, and sensitivity. SpatialEMU also provides Nintendo DS touch input, DOS keyboard and mouse controls, and specialized controls for supported arcade and mahjong titles. LOCAL-NETWORK CABINET LINK Supported SEGA Model 3 titles can create native cabinet-link sessions across multiple devices. Every device runs the same user-provided game locally while the LAN carries only cabinet-link data. Some larger room layouts remain clearly labeled experimental. LOCAL PROGRESS Keep local battery saves and save states for supported systems. Store separate progress for each game and synchronize supported save records through your own FolioSpace Library. IMPORTANT SpatialEMU does not include games, ROMs, BIOS files, firmware, encryption keys, copyrighted game content, or downloads for such content. You must provide files you have the right to use. Compatibility does not imply affiliation with the relevant hardware or game publishers.

Prime unlocks additional supported systems through a monthly subscription, annual subscription, or one-time lifetime purchase. Compatibility varies by game and platform. Subscriptions renew automatically unless canceled. Eligible earlier purchasers retain permanent Prime access after purchase-history verification. Purchasing lifetime Prime does not automatically cancel an existing subscription. Prices and purchase options appear in the app.

emu runs seventeen game systems on one iPhone, from 8-bit cartridges to the disc-based 3D era. There are no cores to download and no configuration files to write. GETTING STARTED TAKES THREE STEPS 1. Pick a backup of a game you own from the Files app. 2. The system is identified from the file's contents, so you never choose one. 3. Tap it in your library and play. Files can stay inside a ZIP or 7z archive, and a CUE and its BIN files can be selected together. If a CUE points at a filename that no longer matches, emu repairs it on import. Large disc images are streamed into place rather than expanded in memory. ONE LIBRARY FOR EVERYTHING Search by name, star what you keep coming back to, and resume from the recent row. Import the same game under a different filename, or as both an archive and its extracted copy, and the CRC-and-size fingerprint still leaves you with a single entry. THE LAYOUT MOVES TO YOUR THUMBS The on-screen pad is multi-touch, with true diagonals and slide-to-change between buttons. Move the pad up or down, and pull the landscape buttons inward or outward. ANY GAMEPAD, MAPPED YOUR WAY Bluetooth and USB controllers connect on their own. Buttons are matched by position rather than by the vendor's printed labels, so a different controller still plays the same way. Reassign a button by pressing it, keep sticky 1P/2P assignment, and tune the stick dead zone. Touch input stays live alongside the gamepad. SAVES HAPPEN QUIETLY, MISTAKES ROLL BACK In-game and memory-card saves are written every 30 seconds, and again when you leave the player. SAVE and LOAD give you a quick state at any moment, and holding REWIND rolls the last seconds back for one more attempt at the jump you just missed. TWO IPHONES, TWO PLAYERS One player hosts and a code appears; the other types it in and joins as player 2. The player joining does not need a copy of the game. The two devices connect directly — gameplay never passes through a server, and a relayed route is detected after connecting and torn down. Two-player games for NES, SNES, PlayStation, Sega Saturn, Nintendo 64, Mega Drive, Master System and PC Engine can be hosted. BRING YOUR OWN GAMES — REQUIREMENTS DIFFER BY SYSTEM No games and no BIOS files are bundled, and nothing can be obtained from inside the app. Use backups of software you are legally entitled to use. Runs with just your game file: NES, SNES, Game Boy / Color, Mega Drive / Genesis, Master System, Game Gear, PC Engine / TurboGrafx-16, WonderSwan / Color, Nintendo 64, GameCube, PlayStation 2, PSP Also needs a BIOS you dumped from your own console: PlayStation, Sega Saturn, Game Boy Advance, Neo Geo Pocket / Color If you are here for Xbox: It needs three files you supply yourself — an MCPX ROM, a compatible Flash BIOS, and a hard-disk image. An unmodified retail Flash BIOS will not boot. Treat Xbox as experimental and for advanced users. ABOUT SPEED GameCube, PlayStation 2, Xbox and Sega Saturn support is experimental. The App Store build runs without a JIT, so how well a game plays depends on the title and your device. Please don't buy on the assumption that a particular game will run smoothly. FREE TO START The free version shows one banner and needs an internet connection. That banner only ever promotes the developer's own apps; there is no tracking-based advertising. A one-time in-app purchase hides it on every device signed in to your Apple Account. iPhone, iOS 17 or later. English and Japanese. emu is built on open-source emulators including ares, PPSSPP, Mupen64Plus, Dolphin, xemu, Play! and Yaba Sanshiro.
