The old Gameboy has a background map of 8x8 tiles, and up to 40 8x8 sprites, all in four-color greyscale. The GB Color has that the same way - you're right, it's 4 colors per 8x8 block and, independently, four colors per sprite. The Gameboy CPU is a custom Z80 (with stuff like I/O removed) running at 4 MHz; the GB Color CPU can run at either 4 or 8 MHz. -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
