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: Lambda at none against TransPlay's shown. TransPlay's advantage is update cadence (every 4 days vs every 5 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
