DuckStation (bios.cpp:208, 397-427), SwanStation (host_interface.cpp: 136-194), rustation (lib.rs:107-160), FS-UAE (rommgr.cpp:92-151), ares (firmware.cpp:116-136) and Altirra (uifirmwarescan.cpp:29-113) scan a folder and identify firmware by hash; Ymir does in its standalone build only. FS-UAE still opens rom.key by name (rommgr.cpp:1397-1498). The export then stops writing their labels into platform lists: Batocera's psx block goes from 106 entries to 10, and System.dat's scph5000.bin keeps its own hashes.

|
|
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.
