I'll second the GBA emulator, there's a huge wealth of good games out there for it. I'll also add a PSX emulator if you can find one, especially if you can pair it with a PS3 controller with a GameKlip (and don't mind carrying all that stuff around). I beat Final Fantasy's 6-9 over about a year of subway commutes.
My Boy plus a bluetooth game pad is just awesome! If I go to the gym I stick my phone on the front of the treadmill and play pokemon while I power walk :)
