PCSX2 does not mandate a specific filename. It scans the entire bios/ directory
|
|
for any file between 4-8 MB that contains a valid romdir structure (RESET + ROMVER entries).
|
|
Common filenames follow the SCPH-XXXXX_BIOS_VYYY_REGION_ZZZ.BIN convention but this is
|
|
not enforced. The file is loaded into the 4 MB ROM region of EE memory.
|
|
|
|
# -- ROM1 (optional, DVD player) --

|
|
pattern: "{biosname}.rom1 or {biosbase}.rom1"

source_ref: "pcsx2/ps2/BiosTools.cpp:214-241"
|
|
note: >
|
|
DVD player ROM. Loaded via LoadExtraRom("rom1"). PCSX2 tries two naming patterns:
|
|
1) Full bios path + ".rom1" appended (e.g. scph70004.bin.rom1)
|
|
2) Bios path with extension replaced (e.g. scph70004.rom1)
|
|
Mapped to EE memory at ROM1 region (0x1FC00000 + 4MB offset).
|
|
Contains DVD player and region detection data (DVDID).
|
|
|
|
# -- ROM2 (optional, Chinese ROM extension) --
|
|
- name: "<biosname>.rom2"
|
|
pattern: "{biosname}.rom2 or {biosbase}.rom2"

max_size: 4194304 # 4 MB (Ps2MemSize::Rom2)
|
|
source_ref: "pcsx2/ps2/BiosTools.cpp:214-241"
|
|
note: >
|
|
Chinese ROM extension. Loaded via LoadExtraRom("rom2"). Same naming convention
|
|
as rom1: tries appended extension first, then replaced extension.
|
|
Only present on Chinese region consoles.
|
|
|
|
# -- NVM / NVRAM (optional, auto-created) --
|
|
- name: "<biosname>.nvm"
|

source_ref: "pcsx2/CDVD/CDVD.cpp:160-238"
|
|
note: >
|
|
EEPROM / NVRAM data. Path derived from BiosPath with extension replaced to ".nvm"
|
|
(cdvdGetNVRAMPath). Contains console configuration: language, timezone, iLink ID,
|
|
region parameters, OSD settings. Auto-created with defaults if missing.
|
|
Two NVM layouts exist: v0.00+ (biosVer 0x000) and v1.70+ (biosVer 0x146).
|
|
|
|
# -- MEC file (optional, auto-created) --
|
|
- name: "<biosname>.mec"
|
|
pattern: "{biosbase}.mec"
|
|
required: false
|
|
size: 4 # u32 s_mecha_version
|
|
source_ref: "pcsx2/CDVD/CDVD.cpp:190-204"
|
|
note: >
|
|
Mechacon (mechanism controller) version file. 4 bytes containing the mecha version
|
|
as a u32 value. Auto-created with DEFAULT_MECHA_VERSION (0x00020603) if missing.
|
|
Path derived from BiosPath with extension replaced to ".mec".

note: >

|
Custom IOP Reboot eXecutable module. Loaded into ROM at offset 0x3C0000 if
|
|
EmuConfig.CurrentIRX is set (path length > 3). Injected at IOP reset (PC=0x1630).
|
|
Used for debugging/development, not needed for normal operation.
|
|
|

note: >
|
|
DEV9 (network adapter / HDD expansion bay) EEPROM data. Fixed filename "eeprom.dat"
|
|
opened from working directory. Contains network adapter configuration.
|
|
Falls back to built-in defaults if file not found. Only relevant when using
|
|
DEV9 features (online play, HDD).

notes: |
|
|
PCSX2 is filename-agnostic for the main BIOS. Detection relies on romdir structure
|
|
parsing inside the binary itself, not on filename or extension. Any file between 4-8 MB
|
|
with a valid romdir (containing at least RESET and ROMVER entries) is accepted.
|
|
|
|
The ROMVER entry encodes: version (2+2 digits), region letter, console/devel flag,
|
|
build date (YYYYMMDD), and is used to determine the BIOS description and region.
|
|
|
|
Companion files (.nvm, .mec) are auto-created with sane defaults if missing.
|
|
ROM1/ROM2 are silently skipped if not found - only the main BIOS binary is strictly required.
|
|
|
|
PCSX2 no longer ships as a libretro core in official builds. The standalone emulator
|
|
is the primary distribution channel.
|
|
|
|
Devel console BIOSes (< ~2.3 MB) lack the OSD and are handled with NoOSD=true flag.
