notes: |
  FS-UAE is an Amiga emulator by Frode Solheim, based on UAE.

  Kickstart ROMs loaded from save_dir/Kickstarts/ (not system_dir).
  base_dir = RETRO_ENVIRONMENT_GET_SAVE_DIRECTORY (paths.c:136).
  Kickstarts/ subdirectory created automatically (paths.c:258-264).
  Also scans AmigaForever/Amiga Files/Shared/rom/.

  ROMs identified by checksum, not by filename.

  Standard Amiga kickstart ROMs (all 512 KB unless noted):
    kick13.rom (A500 Kickstart 1.3, 256 KB)
    kick20.rom (A500+ Kickstart 2.04)
    kick31.rom (A1200 Kickstart 3.1)
    kick40068.A1200 (A1200 Kickstart 3.1.4)
    kick40068.A4000 (A4000 Kickstart 3.1.4)

  The core is marked experimental by upstream. Most users should use PUAE.
