notes: |
|
|
Beetle PC-FX is the libretro port of Mednafen's NEC PC-FX emulation module.
|
|
The core requires a single BIOS file: pcfx.rom (1 MB). The setting
|
|
"pcfx.bios" resolves to the filename "pcfx.rom" via MDFN_GetSettingS()
|
|
in mednafen/settings.c:92-93. The file is loaded from the libretro
|
|
system directory in LoadCommon() (libretro.cpp:367-394).
|
|
|
|
The BIOS is mapped at address 0xFFF00000 and must be exactly 1048576 bytes
|
|
(1024 * 1024). LoadCommon() returns false if the file is missing or the
|
|
wrong size, so the core will not start without it.
|
|
|
|
No other firmware files (fx-scsi.rom, pcfxga.rom, pcfxv101.bin) are
|
|
referenced by this core. Those exist for other PC-FX emulators or
|
|
alternate BIOS versions but are unused here.
|
|
|
|
BIOS loading: libretro.cpp LoadCommon() lines 364-397.
|
|
Setting resolution: mednafen/settings.c MDFN_GetSettingS() lines 90-94.
|
|
BIOS memory: static uint8 *BIOSROM, mapped at 0xFFF00000 (1 MB region).
