I'm just curious on what ROM errors are.


Are they just problems with a single rom on a PCB?


I'm asking as theres a game up for sale for cheap with a rom error U13. Would I just have to find another rom to replace the one that is the problem?

THanks for any help in advance!!!!
 
If it's the ROM/EPROM at fault then replacing it should be easy enough - however, a ROM error can also be caused by a bad socket, broken trace(s) or one or more problems with logic chips. First thing to do is replace the suspect ROM (or if you have an EPROM programmer, read it and compare against the relevant MAME binary).
 
Ahhh, thats good info right there! I think i may buy it if it stays cheap. Might be a an easy fix...or might not, I suppose there all a gamble.
 
Helps if we know what game it's for. :confused: But yeah, it could be EPROM bit-rot, or something else on the board.
