I'm helping a friend revive some brunswick boards. I read the d2764a from a working board and verified them to the saved bin. pulled some d2764a's from a different board, erased, wrote, and verified those. Even though they verified when I try to boot the board with these burned chips it doesn't work. with the original rom set the board still works correctly. Any ideas?

Thank you for the info fusioncliffs.
The only difference is WVCC="6.2V".

Make sure the original chip checksum is same as the copied chip.
