I deglobbed Radica Skateboarder's CPU, but enough epoxy stuck to the die that I can't see the part number. It is the same size as Space Invaders (smaller than Golden Tee), but not identical from what I can see. CubeWorld had a CPU blob and an LCD controller blob. The LCD die is twice as wide and tall as the CPU, since it has 120 segment outputs. Epoxy stuck to them, too; all I could read was Winbond on the CPU die. I'll get some pics after I've got time to clean them off with acid.
