Someone gave me a Street Fighter II board to try to fix. It plays fine, but it's missing all the graphics for the foreground objects (sprites). In test mode, the "Object" test shows just a solid beige screen, while the "Scroll 1/2/3" tests show all the background graphics properly. All the ROMs on the 2nd board have activity on all their pins.
In the apparent absence of schematics available for this board, does anyone here have experience working on this or similar CPS1 games who can give me some suggestions for where to start troubleshooting this?
