Technical notes

Libretro port of Mednafen's PC-FX module. Setting "pcfx.bios" resolves to "pcfx.rom" (mednafen/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.
