I have almost 100 UPD77C25 Chips that are not doing me any good. Because they cannot be recorded. I wonder why there are UPD77C25 chips in white, but they cannot be programmed? I have a programmer capable of programming the UPD77P25. I created some games with these DSPs, but with the UPD77C25, without success. My question is: Is it possible to create some circuit with a ROM that stores the 10kb of the DSP file so that it can work?
