Profiles that read two repositories, a libretro port and its upstream, now prefix each citation with source or upstream, decided by which tree carries the cited value at its pin. The emulator pages use the word to tell libretro glue, emulator code as the port carries it, and the upstream emulator apart.

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.
