SwanStation accepts PS1 (512KB), PS2 (4MB), and PS3 (0x3E66F0) BIOS sizes but only uses the first 512KB. MD5 validates the extracted content, not the full file. List all accepted sizes to eliminate the false size mismatch discrepancy. validation.py: support size as list in emulator profiles. generate_site.py: handle list sizes in emulator page display. All 18 original hash mismatches are now resolved: 0 discrepancies.

notes: |
|
|
Fork of DuckStation maintained by the libretro community after stenzek removed
|
|
libretro support. Frozen at an early DuckStation state.
|
|
|
|
BIOS is required to boot. No HLE fallback.
|
|
ref: src/core/system.cpp:667-674 (GetBIOSImage fails = Shutdown)
|
|
|
|
Auto-detects BIOS by scanning system_dir for files of known sizes.
|
|
ref: src/core/host_interface.cpp:183-243 (FindBIOSImageInDirectory)
|
|
Accepts PS1 (512 KB), PS2 (4 MB), and PS3 (0x3E66F0) BIOS images.
|
|
Only the first 512 KB are loaded (bios.cpp:83, 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 (all PS1 variants).
|
|
ref: src/core/bios.cpp:27-70 (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.
