RetroArch is a frontend for libretro cores; whether another setup works depends on the particular system and hardware. Start with the Libretro guides and the alternatives page.
Compare on a small library
- Launch the same legally obtained game on the target devices and note the emulator or core version.
- Test controller mapping, hotkeys, audio/video synchronization, and performance with the settings you will actually use.
- Back up in-game saves and save states separately. Verify that each imports and loads before deleting anything.
- Check playlists, metadata, shaders, accessibility, and where configuration files are stored.
- Confirm platform-specific support and any BIOS or firmware requirements from official documentation.
A frontend can feel simpler while leaving a favorite game unsupported. Decide with a per-system compatibility table and a reversible save-file migration.
