Is there an emulator for SNES to put on an EZ FLASH that's running in a Game Boy Micro? I know its possible to play NES, but what about SNES? Thanks!
Kind of.

Compatibility for both is not great (certainly no chance of any special chips games), there is no sound, you have layer ordering issues (though you still get those on a lot of far better emulators) and speed is not always the best. It was an amazing feat of programming to get even a handful of SNES games emulated on the GBA but if you are wandering in thinking of something PSP or DStwo level you are not going to like it.
However the GBA earned its sometimes nickname of little SNES with a load of great ports of 16 bit classics so you are often better off looking there.
There is also a pretty good PCE/TG16 emulator, it is far from flawless but good enough for a lot of games and a lot of 16 bit era games ended up with versions on it.
Oh and to round it off there is no Megadrive/genesis emulator either.
