Recently pickup an Arena that boots and plays but with issues. Diagnostics say "Error Prom 2 Game Prom checksum Prom 1 34C4". None of the ground mods have been done. Could they cause this error or should I proceed with getting some known good Roms first?

ok thanks. Unfortunately I don't have a Rom burner. I will contact John Jukes and see if he can hook me up.

Just as a follow up. Cleaning the pot on the power supply board and making sure it was set to 5 volts cleared the Prom2 Error.
