Technical notes

Fork of Mednafen's pce module (accurate, with SuperGrafx and CD support). Separate codebase from mednafen_pce_fast (mednafen/pce/ vs mednafen/pce_fast/). BIOS loaded via PCE_LoadCD() at CD-ROM load time. Core option "pce_cdbios" selects which card image to use (default: System Card 3). DetectGECD() auto-detects Games Express discs and overrides to gexpress.pce. Arcade Card mode (pce_arcadecard option, enabled by default) extends System Card 3 with extra RAM mapping. No hash or size validation on BIOS load. Upstream pce module has configurable pce.cdbios/pce.gecdbios string settings, and the 6-option dropdown is a libretro addition.
