This loop takes roughly 24200 cycles, giving + 2500 + (24200 - 2500) * 2 * 60 = 2754000 = 2.75MHz for the CPU speed, + assuming 60 fps and a 2500 cycle VBLANK period. + This should be easy to check since the schematics are available, . + - I think theglob2 is earlier than theglob. They only differ in one routine, + but it appears to be a bug fix. Also, theglob3 appears to be even older. + + To Do: + + - Super Blob uses a busy loop during the color test to split the screen + between the two palettes.
