start converting spbactn to tilemaps, it's now clear that the prototype uploads the backgrounds once and uses the scroll regs (not hooked up) whereas the release version just uploads them as it needs them before each level. I wonder if the extra z80 rom + gfx on the proto are for a 2nd screen, some kind of fake dmd?
