BIOS loaded via HuCLoadCD() at CD-ROM load time. Core option \"pce_fast_cdbios\" selects which card image to use (default: System Card 3). No Games Express auto-detection (unlike beetle_pce), so the user must select manually. No hash or size validation on BIOS load. Upstream pce_fast module only has a single pce_fast.cdbios string setting: the 6-option dropdown is a libretro addition.\n",
