Yeah, no modding required. Just buy the cheapest flash cart you can find. I have one of the old ones before they supported SD cards and the like - mine has internal storage...and not much of it at all...I think about 32MB total. Fortunately that's plenty for just your favorite NES games.
I use Pocket NES as the emulator one mine: http://www.pocketnes.org/
There's also an SNES emulator for it as well, but it was always pretty limited due to the limitations of the GBA. Maybe it got better, I'm not sure. It's been a long time since I tried it out.
