I have a Double Dragon board that I have been messing around with and I'm complete at a loss at the current moment. When I supply +5v to the board it will give a ROM 3 error on the screen at start up and then glitch out in a random fashion soon after. If I increase voltage to 5.8v the ROM 3 error will still be present but the game will run 90% of the time. Sometimes after running at the higher voltage for a while the ROM 3 error will go away completely.
I put a brand new power supply into the cab. Looking around the board nothing looks obviously broken but some ICs do seem to get very hot when running at 5v... any suggestions?
