Troubleshooting Crime Fighters Board with Sound and Sprite Issues
Hey guys,
I picked up a Crime Fighters board as is a while back and now that I have gotten around to testing it I have found some issues with it. There are both graphics and sound problems with it. When I turn the machine on there is a high pitch static sound the whole time the game is running. There is no sound or sound effects. There is also a graphics problem. When the game boots up the name crime fighters is basically all blocks or verticle lines. During game play the characters also display as blocks. I ran a self test on the game and at the first self test screen it is just full of blocks. When I skip to the ROM test screen it only tests 2 roms and they both display as bad. These are the ROMS that are failing: 821K04, and 821K05. In the sound menu some of the sounds work. I have attached some pictures showing the issue. I have removed and reseated both socketed chips and have also cleaned them before putting them back in but this does not resolve the issue. I am thinking about getting in touch with hobbyroms to see if they have replacements for ROMS 821K04 and 821K05. Anybody have thoughts or ideas on this? Or any advice on any other possible issues? I'm assuming that these roms have the character sprites in them but would that also affect the sound? Thanks - Justin
