I've got two Nintendo Helifire board sets which I'm working on, one is working perfectly, the second is giving me an odd minor color issue on a submarine.
The troublesome board set has a submarine which has lost its purple color, and appears like it's in stealth mode. The normal coloring of the sub is a combo of bit of a background color, let's call it a shadow. In front of that shadow is a pink sub shape. The pink color is lost so I'm just looking at the shadow at this point giving it the appearance of an invisible/stealth sub.
I am guessing the pink shadow is stored on some rom chip in here, but I have swapped every rom chip with the other boards ROMs and the invisible problem does go not with the ROM chips to the other board. So maybe there's a chip in here is not causing the purple to be visible?
