Argh, chankast is pissing me off. When I goto play some games it gives me the AV cable not compatible error. So I go and I switch the cable to NTSC like others have said. When I do that after the DC logo, during the Sega logo screen, it shows the sega logo/copyright in the top half of the screen and the bottom half is black and chankast freezes completely. I've tried 2 sets of bios, I've tried with multiple games and redownloaded it. No progress it still is broken.
Picture of what it looks like:
What is going on!? Please help!
