hello friends.
I hope I don't cause any inconvenience if I expose my problem on this site.
I just acquired this fully functional cps1 pcb but the pcb had the daimakaimura game programmed but I already have that original game and I want to leave this pcb in its original state because the c board is from an sf2ce and I don't have that game yet . I downloaded the world 920513 rom, I used 27c4002 memories for all the programming because the pcb is an ep-rom type and for the sound I used 1x27c512 and 2x27c1001, I burned a gal16v8d for location 1a with the jed S9263b.jed format but when turned on I have graphic problems on the pcb.
Is there a special sf2ce rom for this type of jedec ep-rom type pcb? I already checked the programming again and it is well burned and well inserted in its locations.
I added that the 3 floors or 3 boards work correctly with any other game, the problem is in the programming and I think it is the wrong rom.
I hope I don't cause any inconvenience if I expose my problem on this site.
