Windows tool to copy your ROMs from RomStation to conventional folder structures compatible with RetroArch, Lakka, and Anbernic handheld devices.
RomStation centralizes your retro emulators and ROMs library into a single interface. But when you want to use your ROMs with RetroArch, on an Anbernic handheld console, or any other frontend, you face a problem: these targets expect a conventional folder structure (/roms/psx, /roms/snes, /roms/gba, etc.) that is very different from the one used by RomStation.
RomStation Rebase automates this copy while respecting the conventions expected by each target — without ever modifying your RomStation installation.
⚠️ RomStation Rebase always works in copy mode. Your RomStation installation remains intact and fully functional.
Two versions are available on the Releases page — pick the one you prefer:
- MSI Installer (recommended): proper Windows installation with Start menu shortcut and uninstaller
- Portable ZIP: extract anywhere and run
RomStationRebase.exe, no installation required
The most recent version is always available on the latest release page.
- Windows 10 or 11 (64-bit)
- RomStation installed (setup.exe version or portable ZIP — both are supported)
- RomStation must have been launched at least once for its database to be initialized
The application embeds the .NET 10 runtime — no additional installation required.
- Launch RomStation Rebase
- Select the games you want to copy (individual checkboxes, or "Select all" per system)
- Click Rebase to...
- Choose the target folder (SD card, USB drive, external disk...)
- Select the target architecture: RetroArch / Lakka / ArkOS / ...
- Click Start
ROMs are copied using the folder structure expected by your target device.
- Two display modes: grid (covers) or detailed list
- Filter by system: only show the platforms you care about
- Smart RomStation detection: automatic via Windows registry, or manual selection for portable ZIP installations
- Parallel copying: multiple files copied simultaneously, optimized speed
- Duplicate handling: configurable policy (skip or overwrite)
- Automatic retries on transient failures (network drives, unstable USB...)
- Preferences memory: last target folder, target architecture and settings are restored on each launch
- Localized interface: French and English (automatic detection based on system language)
- Execution report: real-time tracking with per-game status (done, skipped, failed) and log export
- C# / WPF — native Windows interface with MVVM pattern
- .NET 10 — self-contained, no external dependency required
- IKVM — Java ↔ .NET bridge to access the RomStation Apache Derby database
- Apache Derby — read-only access on a local copy of the database
The RomStation database is always worked on via a copy. The original remains untouched.
