-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.
