Hello all. I am restoring a Plachoice 10. I have a few boards that have bad mask rom chips. Either the graphics are corrupt (bad U1) or the titles display until selected. The system then refreshes and that game is gone (bad U2). My question is: can I replace a mask rom with an eprom chip? I see lots of people that can burn games onto eproms but no one says anything about mask roms. I am not looking to swap the games out with different games. I just want a functional copy. I have taken the roms out and reset them to make sure it wasn't something simple like a loose chip. I am assuming the PCB is good because the system will display info or corrupted graphics. Interchangeable chips would make this an easy fix. Any thoughts or know how on this would be great.
Thanks!
Thanks!
