Retro Trans makes open toolchains and English fan translation patches for Japanese games that never left Japan: mostly Super Robot Wars, Macross and Another Century's Episode, plus RPGs across PS1, PS2, PS3, PSP, Vita, Dreamcast, GameCube and PC.
Every project ships as a small patch you apply to your own disc dump (xdelta for most games, DCP for some Dreamcast discs). We never distribute game images or Japanese script dumps. Patches are verified against exact source and output hashes.
- Download Retro Trans for Windows 10/11 (standalone EXE, nothing else to install).
- Open the Automatic tab, click Refresh catalog and select your original Japanese ISO / CHD / BIN / CUE.
- Choose Latest, pick an output filename and click Patch. The app finds the right patch (fresh install or upgrade), downloads it and verifies the result.
Prefer doing it by hand? xdelta releases also work with Delta Patcher or xdelta3, and DCP releases with the app's DCP tab. The project's README lists the hashes. Vita releases also support Vita3K and hardware rePatch through the app.

Note
Most projects are work in progress. The version number tells you how far along a game is:
| Version | What it means |
|---|---|
| 0.1 – 0.8 | Early or in-progress builds. Playable, but routes haven't been fully playtested yet. |
| 0.9.x | At least one route has been fully playtested from start to finish. |
| 1.0.x | The whole translation has been fully proofread by a human. |
Each release's notes say exactly what has been checked.
We'd love more players on these games. You can help by:
- Playtesting a route and opening an issue in that game's repo. Include the patch version, emulator, chapter or stage, and a screenshot.
- Proofreading the English against the Japanese. The English scripts are in each repo, and the
docs/folder explains the workflow. - Porting the tools to another game or language. Every toolchain is open, so fork away.
