I have an systems architecture I believe will work well on the GBA for emulating a '2600.  Yes, it's a 16.78MHz processor - an ARM7TDMI to be precise.  I've been thinking about the emulator architecture for some time now, and have started the implementation.  The only real issue for me is accurately emulating the '2600;  getting a basic emulation is straightforward.
The plan is to implement a realtime bi-linear filter on the screen so the Atari screen will fit on the GBA screen (240 x 160) without the need to scroll around (though this is optional).

Hmmm...doesn't the GBA run close to 16.78 MHz???  Hmmmm......

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