working on a donkey kong pcb
everything works but i have a line above the ladders
any idea of what it could be
ive checked all the roms so i know thats not it
i think its a 74ls chip but im not sure
Can't help with what's causing it, but there's a big black box that width that covers the area above the top of DK's ladders. This is so he disappears behind it as he walks up. If it wasn't there, there'd be 2 pieces of girder above the ladders (you see them for 1 frame at the start of each board before the black box covers them), and he'd disappear in pieces as he crossed those girder pieces above the ladder. It does this in Crazy Kong too, but on DK, instead of fixing what caused it, they just covered it up with a black box I think it's a sprite (probably in the graphic ROM's), but I'm not 100% sure.
