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.

LetsNES — The Ultimate Retro Emulator for iPhone, iPad & Mac. We’ve kept the raw soul of the classic NES & SNES alive, but wrapped it in a stunning, high-res pixel art UI and skeuomorphic console design that’ll hit you right in the feels. No cold, boring modern menus here. No complex netplay setups. From the vibes to the gameplay, this is top-tier stuff. Killer Features: 【Online Co-op (Anywhere, Anytime)】 Wanna play with an old buddy who lives miles away? LetsNES makes remote co-op as easy as texting. Just hit "Create Room", send the code to your friend, and boom—P2 joins the game. No annoying network configuration, no tech headache. Powered by our rebuilt netplay protocol, you get crazy low latency for those intense levels. Perfect for streamers and party nights too! 【Gorgeous Pixel Art & Skeuomorphic UI】 Every menu, icon, and transition is custom-built with retro aesthetics. It looks beautifully nostalgic but feels incredibly slick and sharp on modern high-res screens. 【Rewind & Instant Save (No Rage Quitting)】 Mess up a crazy hard jump? Just hit rewind and bend time to try again. With instant saves and loads, you can pause whenever life happens and pick right back up later. 【Tactile Retro Controller Vibes】 We spent forever tweaking our virtual gamepad to recreate that classic tactile feel. With fine-tuned layouts, rapid response times, and premium haptic feedback, you’ll actually feel the clicks on your screen. (Physical controllers/keyboard mapping are also fully supported!). Heads Up (Legal Disclaimer): LetsNES is strictly an emulator / file player. No games or ROMs are bundled with the app. You gotta bring your own legally acquired ROMs (.nes / .sfc format) to play. Just drop them in via the built-in Files app or transfer them from your computer, and you're good to go!
