Hi to everyone
I have some MV-1 (1 slot) Neogeo boards that previously have the famous BACK UP ERROR, so i change one or both 58256 chips on those boards but that error now changes to MEMORY CARD ERROR. The problem is this boards doesn´t came with a memory card slot or any port to use them.
I changed the 58256 chips with a pair of replacements 43256 chips but have same problem, i checked continuity for broken traces and all seems to be ok, checked for shorted pins, transistors, diodes, capacitor, etc, but all of those have correct readings.
At this point im stuck with this error so I just wonder if anyone here knows how to fix that error.
Thanks
