I posted this in the Krikzz forum and he did respond but hasn’t offered any troubleshooting tips yet (he did respond once and hoping he responds again), but I figured I’d try here.
I have a Mega SG with the Smokemonster jailbreak but wanted the Sega CD stuff too, so I bought the MED Pro. I can’t get it to play Euro or Japanese CD games. I’ve downloaded the appropriate BIOS’ and renamed them as the instructions state. I’ve tried two Japanese BIOS but still nothing. Black screen or frozen Mega CD load screen every time. Anyone know why this might be happening? I've also turned off MegaKey in the event it was causing any problems. Still nothing. Thanks
