I have a 2210 as well. The thing will run an SNES emulator, but it really doesn't have enough buttons to play the games without hassle. NES is another story. I use pocketNES for that one. I also got Simcity 2000 off of a P2P *cough* er Best Buy down the road. It's pretty cool, even with the small screen.
This site has even more stuff on it.
