I've been looking to learn how to write an emulator. Does anyone know a really simple open source emulator? Preferably for the GP2x.
 
As a learning exercise, your probably better off doing it on your PC where you have far more resources, and then starting the emulator from scratch rather than using an existing one.

For example, http://www.cse.unsw.edu.au/~cs1721/05s2/emu/emu.html has a good description an example projects to test your emulator with based on the AVR instruction set.
 
Modifying someone else's emulator is a much different (simpler) experience than writing one, although it's unclear if you want another emulator to do this or to use as a reference for comparison. If you want to know the easiest gaming platform to emulate then Gameboy and SMS are up there.
 
I have found that a really nice little emulator for understanding the basics is Oriculator..

It helps that I've always loved the Oric machines, but this code is pretty well written and understandable. machine.c is itself a very nice bit of work to read .. and if you feel up for the job, there are still bits to be added to the emu to make it complete.
