Ully, did you try to "mingle" the boards. So use the video board of the original paperbay on the other one and vice versa ?
It's just to isolate the problem to one board.
right now i'm using the championship sprint video board in the paperboy with the rams / roms switched over. haven't had the time to test the PB video board in the CS yet, because it's still in storage!
When will you start working on Death Race, that one will also be an awesome project to follow.
right now i'm working on the games i have up here, that is defender, pac-man and i've just recently started work on the berzerk. death race (and championship sprint) are next in line though, can't wait to get started on those either. the problem is that i can't bring an unlimited amount of games up here, i first have to clear some space (that is: move games out) in my "hobby room" so that the next one can move in.
btw, i want to thank all of you guys again for the nice comments you always find for my work, i really appreciate it and it motivates me to do things even better
