Re: Super Gold Card (Clone)

Because of that system and CPU clock may be different from 24 MHz. Have you tried any other clock speeds? What worked? I tried several clock generator. 25 MHz - works 32 MHz - started and crashed after several seconds. 20 MHz - works 16 MHz - started but dont work properly, have video issues in HiR...
