Technical notes

FS-UAE is an Amiga emulator by Frode Solheim, based on UAE/WinUAE.

Standalone: scans --kickstarts_dir for .rom/.bin files (default: Documents/FS-UAE/Kickstarts/). Batocera overrides to bios/amiga/ via --kickstarts_dir (fsuaePaths.py:8, fsuaeGenerator.py:68). Libretro port: scans save_dir/fsuae/Kickstarts/ (frozen at v2.7.15). Identification by SHA-1 checksum, not filename (rommgr.cpp:92-151, romservice.py:78-91). AROS kickstart (1 MB) compiled into binary as fallback for all models (rommgr.cpp:112). rom.key searched in kickstart dir and multiple fallback paths (rommgr.cpp:1397-1498).

Supported models: A1000, A500, A500+, A600, A1200, A3000, A4000, A4000T, CD32, CDTV. Default model is A500. Each model auto-selects its kickstart via quickstart mechanism (cfgfile.cpp:9468-9517 for A500, cfgfile.cpp:9732-9791 for dispatch).

ROM database shared between standalone and libretro (same WinUAE-derived rommgr.cpp). Upstream v5.0.7 has a larger database (332 vs ~200 ROM IDs in libretro port). Also supports Arcadia, ALG, freezer cartridges, SCSI/CPU board ROMs when configured.
