Hi Guys:
I have managed to restore some life to my circus charlie board(Konami) which had a screen full of horizontal lines(faulty 74LS02 12C ).I now have most foreground sprites such as the stars on title screen and in-game i have charlie,monkeys,pots,etc but the background is blank and green.(no score displayed either).I have replaced all roms/rams with no change.
Any of you guys point me in the right area on the circuit diagram to what controlls background graphics,im lost with these specialised Konami ic`s.
