Technical notes

Fork of DuckStation maintained by the libretro community after stenzek removed libretro support. Frozen at an early DuckStation state.

Boot loads a BIOS image. When none is found a built-in OpenBIOS copy (dep/openbios) boots instead. ref: src/core/system.cpp:650,678-682

Auto-detects BIOS by scanning system_dir for files of known sizes. ref: src/core/host_interface.cpp:136-194 (FindBIOSImageInDirectory) Accepts PS1 (512 KB), PS2 (4 MB), and PS3 (0x3E66F0) BIOS images. Only the first 512 KB are loaded (src/core/bios.cpp:84, Image(BIOS_SIZE)). ref: src/core/bios.h:9 (BIOS_SIZE=0x80000, BIOS_SIZE_PS2=0x400000, BIOS_SIZE_PS3=0x3E66F0)

27 known BIOS entries identified by MD5 hash. ref: src/core/bios.cpp:28-71 (s_image_infos) Each entry has: description, region, hash, patch_compatible flag.

Upstream DuckStation has evolved significantly (105 entries, PS2 BIOS, OpenBIOS, priority system). SwanStation is frozen at the fork point.
