Hi everyone. I'm trying to convert GTI Club to Solar Assault. both games used the same pcb layout. I burned all eeproms and set the eeprom 10K from 1M to 4M. Eeprom check is all okay, but I can't initialize the 24G eeprom by pressing test button.. i got always "Magic Number illegal".. who knows what this means and is there a solution to fox it?

i got the same issue in mame when I copy the nvram of gti Club to Solar assault and trying to initializenthe eeprom. Seems I have to desolder it and burn the data on the eprom directly from mame.


Now it works. It is necessary to burn the nvram to the 95c56 (x16) directly. Now it works.
