Is there an alternative way to wire SLROM boards? I have a rom, it is MMC1, It splits into 2 files, prg/chr, so it is a SLROM board.....When I wire it up by the directions below, The title screen works fine, but when you start the game, the screen will screen will just go blank. The rom works great on the pc. I have tried 3 different SLROM Boards, and they all do the same. I have also tested other MMC1/PRG/CHR games, and they work great on the boards, but this one does not. So I was just wondering, is there an alternative to below? Thanks!
