HLE BIOS built-in: core option pcsx_rearmed_bios = "HLE" bypasses real BIOS entirely.
|
|
Default is "auto" which searches system dir for listed filenames, then scans all files.
|
|
Region detection reads bytes at offset 0x7ff51: " E" = EU, " J" = JP, else US.
|
|
Three CRC32 hardcoded as JP override: 0x18D0F7D8, 0x3B601FC8, 0x3539DEF6 (psxonpsp, scph1000).
|
|
BIOS validity check: byte pattern at offset 1 (\x00\x08\x3c\x3f) or string "PS compatible" at 0x12c.
|
|
Files named "unirom" (case-insensitive) are explicitly skipped.
|
|
Region fallback: if the matching-region BIOS is missing, any available region BIOS is used over HLE.
|
|
Three region slots: US (index 0), JP (index 1), EU (index 2) stored in Config.Bios[].

# -- Dynamic scan fallback --
|

# After exhausting listed_bios[], the core calls find_any_bios() which scans
|
|
# the entire system directory via opendir/readdir. Any 512 KB file passing the
|
|
# validity check (magic bytes or "PS compatible" string) is accepted and assigned
|
|
# to the detected region slot. This means scph1000.bin, scph3000.bin, scph7002.bin,
|
|
# scph7502.bin, etc. all work without being explicitly listed.
