Yes, DC can work without GD drive, you need just resonator 33.8688MHz for AICA on GD socket pin B23 = CDDA_CLK

ISO Loader now works as with stock BIOS?
Region Changer doesn't work with custom BIOS, but this mod will switch the custom BIOS to stock BIOS immediately after boot.
Therefore, it is strange. Maybe your PIC doesn't work?
