Recently purchased a jvc on ebay, disks work great, just finished lunar, had a blast playing it 20yrs later. Anyway; disks work 100% no issues, but i cant seem to get any of my genesis carts to work. Its not the carts themselves because they work fine on my model 1&3. I managed to get sonic 2 to boot once but all the other either display a blackscreen or go right to the jvc disk bios. Any feeback is much appreciated, thanks asmg!
