I bought a USB adapter that allows one to connect his PS2 controller (the Dual Shock 2), to the computer and use it as a gamepad. And IMO, the Dual Shock 2 is one of the best controllers ever made.
I use zsnes to read SNES emulated games, and have been having a blast with Donkey Kong Country, Super Mario World, Mario Kart, and next I'm gonna download Killer Instinct.
