RomStation Rebase (RSRebase) is a Windows tool that copies games from a RomStation library to an SD card or a folder, arranged and named the way a handheld or a frontend expects them: ArkOS and dArkOS, RetroArch, Batocera, EmulationStation, ES-DE, Onion, Cocoon, stock Anbernic firmware.
RomStation is never modified. RSRebase always works on copies.
RomStation stores its games in a structure of its own, with internal file names. Frontends and handhelds expect something else:
psx/Alundra.m3u
psx/.Alundra/…
snes/Secret of Mana.zip
snes/images/Secret of Mana-image.png
snes/gamelist.xml
- Browse the RomStation library and check the games to copy
- Copy to the destination following a preconfigured target architecture: folder names, extraction, M3U playlists, covers and metadata
- Convert files during the copy with an external tool (GDI to CHD with chdman, for example)
- Save a preset: the checked games and the rebase settings in a
.rsrgpfile - Keep a detailed log of every rebase
RSRebase does not transfer the saves made in RomStation, and copies neither BIOS files nor emulators: see Limitations.
- It was co-written with an AI: Claude Code, Anthropic's Claude Fable 5.1 model
- Device testing was done on an Anbernic RG353V running dArkOS. The other target architectures follow each system's documentation
