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.

Purchasing lifetime Prime does not automatically cancel an existing subscription. Prices and purchase options appear in the app.

The retro classics you gave up on because you couldn't read them — play them and read them. The app reads the dialogue as it appears and lays the translation over it, in place. No dictionary in the other hand, no walkthrough on a second screen. Twelve consoles, from Game Boy Advance to Dreamcast and PSP, in one app. ■ 12 CONSOLES, ONE APP — STILL FOCUSED ON ONE GAME · Pick a console on the first screen and get a screen made for it alone: core, aspect ratio, controls, translation area and game packs tuned to that console, and a library of only its games. · Switch any time from the top-left button; the app reopens on the console you played last. Imported games are sorted onto the right console automatically. ■ TRANSLATION, RIGHT ON THE SCREEN · Text is recognized where it stands, and the translation covers it — you never leave the game. · Japanese and English source text into 14 languages. · Advanced translation — AI that understands the game's context and tone, and fixes misread characters along the way. Free 5 times a day; unlimited with Pro, which also adds offline On-device AI (a model you download). · Set a translation area per game. Mark the dialogue box and HUD numbers stop getting translated. · Freeze & Translate — when dialogue runs past too fast, hold the frame and read it at your pace. · 601 game packs — per-title glossaries of names, tone and plot, so translations land close to the original. ■ SUPPORTED CONSOLES · Game Boy Advance — .gba · Game Boy — .gb, .gbc · NES · Famicom — .nes · SNES · Super Famicom — .sfc, .smc · Mega Drive · Genesis — .md, .gen, .smd, .cue, .chd · PlayStation · PS1 — .cue, .chd, .pbp, .exe, .m3u · Sega Saturn — .cue, .chd, .m3u · Dreamcast — .cue, .gdi, .chd, .cdi · PlayStation Portable · PSP — .iso, .cso, .pbp, .chd · PC Engine · TurboGrafx-16 — .pce, .sgx, .cue, .chd · WonderSwan — .ws, .wsc · Game Gear — .gg, .sms, .sg · PlayStation, Sega Saturn and Dreamcast need a console BIOS file; Mega Drive and PC Engine only for CD games. BIOS files are copyrighted and not included — dump them from hardware you own. · Fast-forward up to 10× (4× on PS1, Saturn, Dreamcast and PSP) · Snapshots at any moment · Runs on iPhone, iPad, Mac, Apple TV and Apple Vision Pro. ■ ALSO INSIDE · Time Machine — auto-saves as you play (every minute by default) so you can jump back to the moment you missed. · Box-art library — your games shown by their covers, fetched automatically. · Wi-Fi import from your computer's browser. No cable, no iTunes. · Bluetooth gamepads with button mapping per pad and per game; a movable, resizable on-screen controller. · Turbo buttons — the ones you pick fire repeatedly while held. · Cloud backup, plus direct transfer from your other iPhone, iPad or Mac on the same Wi-Fi. · Play statistics — what you played, and for how long. ■ APP LANGUAGES English · 한국어 · 日本語 · 简体中文 · 繁體中文 · Español · Français · Deutsch · Italiano · Português (Brasil) · ไทย ■ PRO SUBSCRIPTION · Solo — every Pro feature for one console, one console at a time. · All-Pass — Pro on all 12 consoles. · Your first subscription starts with a 7-day free trial (once per account). · Prices are shown in your local currency inside the app. · Subscriptions renew automatically at the same price unless cancelled at least 24 hours before the current period ends.

Verdict

The call

The clearest difference is ads: SpatialEMU at none against TransPlay's shown. SpatialEMU also leads on device support (6 vs 2). TransPlay's advantage is update cadence (every 4 days vs every 11 days). On price, in-app purchases and iOS requirement there is nothing between them.
