Technical notes

Frozen snapshot of PUAE at WinUAE 2.6.1 era. Less accurate than current PUAE (5.x), intended for weaker devices. BIOS handling is identical to the current version.

PUAE is a port of UAE (Unix Amiga Emulator) to libretro, continuing E-UAE. Emulates A500, 500+, 600, 1200, 2000, 4000, CD32, and CDTV. Kickstart ROMs are loaded from the RetroArch system directory.

AROS (open-source Kickstart replacement) is available as a built-in fallback when no Kickstart ROM is found. Compatibility is limited compared to real ROMs.

The core scans the system directory for files starting with "kick", "amiga-os", or "KS ROM". Each filename is matched against a table of known naming conventions: standard (kick.A), Amiga Forever (amiga-os-.rom), and TOSEC (Kickstart v.rom). The first valid match is used.

Default kickstart per model (automatic selection): A500, A500OG, A2000OG, CDTV -> kick34005.A500 (KS 1.3) A500+ -> kick37175.A500 (KS 2.04) A600 -> kick40063.A600 (KS 3.1) A1200, A1200OG -> kick40068.A1200 (KS 3.1) A2000 -> kick40063.A600 (KS 3.1) A4030, A4040 -> kick40068.A4000 (KS 3.1) CD32, CD32FR -> kick40060.CD32 (KS 3.1) CDTV (ext) -> kick34005.CDTV CD32 (ext) -> kick40060.CD32.ext

Extended ROM handling: CD32 and CDTV require an extended ROM in addition to the main kickstart. If the main ROM filesize is <= 512 KB, the extended ROM is loaded separately. Combined ROMs (main + ext in one file) skip the extended ROM search.

WHDLoad support copies kick33180.A500, kick34005.A500, kick40063.A600, kick40068.A1200 into saves/WHDLoad/Devs/Kickstarts/ for use by WHDLoad slave files. Also copies rom.key (Amiga Forever decryption) and WHDLoad.key (license) from the system directory.

ROM search order (libretro-core.c retro_config_kickstart): 1. Exact filename in system directory 2. Amiga Forever naming (amiga-os-*.rom) 3. TOSEC modified naming (with [!] suffix) 4. TOSEC naming (without [!] suffix)

capsimg.so/capsimg.dll is an optional shared library for IPF floppy image support (SPS/CAPS format). Not a BIOS file, loaded dynamically at runtime.
