- The only gotcha to the MIPs comparison is that the 9900 can do a lot more in one instruction than the 6502, thanks to a memory-to-memory architecture. You don't have to use registers at all for many instructions, and if you do, you get 16 general purpose registers at a time anywhere in RAM you want. But yeah, the machine isn't quick enough to overrun the VDP except in a couple of very contrived cases - mostly because of the 8-bit to 16-bit multiplexer which eats 4 cycles for every memory access. ;)
