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.
