    I only ordered 6 SN74LVC4245A. Flashes 3 and 4 are different chips are they? Preflashed on your end or something I can buy and fit?

    "checking the flashes with the specific romset that we have for that" ? Is there a diagnostics romset I was not aware about? Please point me towards them ill put them on the SD and test straight away.

    I'll beep out the socket pins to the edge connector and see if any are missing. What do the resistor arrays do? Could it be an issue there?

    Yes, the CHAR board is independent. You can swap tile ROMs as well with the game still booting. You could try burning P1 into a different EPROM, in case the one you've got is slightly dodgy. The only other thing is the connection to the EPROM, either a…
