|
|
Fork of Mednafen's pce_fast module with SuperGrafx and CD support.
|
|
Separate codebase from beetle_pce (mednafen/pce_fast/ vs mednafen/pce/).
|
|
BIOS loaded via HuC_LoadCD() at CD-ROM load time. Core option "sgx_cdbios"
|
|
selects which card image to use (default: System Card 3).
|
|
DetectGECD() auto-detects Games Express discs and overrides to gexpress.pce.
|
|
DetectSGXCD() detects SuperGrafx CD titles via magic bytes.
|
|
Arcade Card mode (sgx_arcadecard option, not exposed) extends System Card 3
|
|
with extra RAM mapping.
|
|
No hash or size validation on BIOS load.
|
|
Upstream pce_fast module has a single pce_fast.cdbios string setting;
|
|
the 4-option dropdown is a libretro addition. Upstream has no separate
|
|
gecdbios setting (unlike the accurate pce module).
