My Tron is putting lines through all of the the sprites. I replaced my interconnect cables and I still have the smae exact issue. What should I try next?
Try pressing in all the roms first in their sockets. Sometimes with the expansion and contraction of the board from heating and cooling they can walk right out of the sockets. If that does not work then remove each rom one at a time and clean the contacts and sockets and reinsert. Make sure you line up the notch on each rom the same as it was when you removed it when you go to reinsert it. It that does not work check the solder joints on each rom socket for cold joints or cracks, reflowing them would not hurt. It that yeilds no results then replace the old roms with new ones. www.hobbyroms will sell you replacements.
It could very well be one of the 93422's on the VidGen board, or it could be one or more of the VidGen ROMs. Does it look like the bottom picture in my third post in this thread? http://forums.arcade-museum.com/showthread.php?t=218828
I pulled the video roms and they were out of order and also 2 were corrupted, one just by one bit, the other was severely off. Here is where it gets interesting, no matter what I do, I can't get them to erase. Currently out of the 2764 roms, but I do have some on the way so I will try those when they get in.
