notes: >
  Libretro port of Mednafen's PC-FX module. Setting "pcfx.bios" resolves
  to "pcfx.rom" (settings.c:92). LoadCommon() loads the file, validates
  size (1048576 bytes), and maps it at 0xFFF00000. Core won't start
  without it. No hash validation. Upstream Mednafen also supports an
  FX-SCSI ROM (pcfx.fxscsi setting, developer-only) not present in
  this port.
