I have a Super Punch-Out board set that I've been troubleshooting. I believe I've narrowed my problems down to the set of EPROMs located on the CPU board. However, I'm not sure if I'm programming the EPROMs correctly. I'm currently using a Willem GQ-4x4 and am trying to program Mitsubishi M5L2764K EPROMs (Labeled as 8H 8J, 8K, and 8L on the board), as well as HN4827128G-25 EPROMs (Labeled as 8F). I've tried using generic devices as well as the specific devices listed under Mitsubishi, but haven't had any luck. I've kept all the settings for file format as .bin, read mode as normal, fill mode as normal, and file offset as 000000. EPROMs verify after burning. I'm currently using MAME files from Emu paradise to burn. If anyone has had experience programming these EPROMs, specifically for Super Punch-Out, it would be greatly appreciated if you could briefly walk me through programming my EPROMs. Thanks for your assistance.
