I'm trying to burn the SMB high-score/save kit info to the 6D/1D rom. I saved the original data, which means my burner read the rom fine but I can't for the life of me get it to burn the high-score data. I can burn the data just fine to every other 28-pin chip I've tried, but the original 2764 chip that was on the board that I erased will not accept the new data.
Are the original Nintendo chips write-protected? Am I missing something? Are they a one-time only burn type of thing?
Any help would be appreciated. Thanks!
