It's not just the frequency..... 18Mhz on a 8051 is wildly different to
18Mhz on an AVR Risc .....

How many instructions per second do you think it would take to create a 100%
accurate 60fps 2600 emulation? I'm talking about being able to read the
collision registers in mid scanline, Cosmic Ark stars, and all the rest of
that stuff that 1st gen emulations like Action Pack could never pull off on
486/66 class hardware (which is probably equivalent to GBA throughput).
I don't think it would matter if it were an 18mhz 256-bit processor, it's
probably not going to be fast enough to do a perfect 2600 emulation,
especially when you also consider that it is going to have to scale the
final bitmap down to the GBA's screen.
