Technical notes

DuckStation auto-detects BIOS by MD5 hash from a flat scan of the BIOS directory. ref: src/core/bios.cpp:460-482 (FindBIOSImagesInDirectory — scans all files by size) ref: src/core/bios.cpp:208 (MD5Digest::HashData identification)

Accepts PS1 (512 KB), PS2 (4 MB), and PS3 (0x3E66F0) BIOS images. ref: src/core/bios.h:24-26 (BIOS_SIZE, BIOS_SIZE_PS2, BIOS_SIZE_PS3) Only the first 512 KB are mapped (bios.cpp:212).

105 known BIOS entries: 24 PS1 + 80 PS2 (identified by MD5) + 1 OpenBIOS (by signature). ref: src/core/bios.cpp:34-139 (s_image_info_by_hash) Each image has: region, region_check, fast_boot_patch type, priority score. Lower priority = preferred. PS2 deprioritized (>= 100) for dynamic fast boot. Late PAL deprioritized (>= 150) due to additional regional checks. OpenBIOS detected by signature at offset 0x78, not by hash. ref: src/core/bios.cpp:142-147

Standalone: BIOS dir = EmuFolders::Bios (configurable, default bios/). ref: src/core/bios.cpp:375,380 Libretro: BIOS dir = RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY (flat). The libretro core was removed by the author (license change to non-commercial). The .info file and buildbot builds still exist from community forks.
