Toying with emulators and such I've become able to not only play N64 games on my computer, but with a N64 controller straight from the system itself. I've been playing like this for a while now, it's a real treat to try the games I never got to play as well as some of my old favorites.

N64 emulator of choice: Project 64.

Also, just today I managed to hook up a Guitar Hero 2 controller into my PC for guitar action on a Guitar Hero maker/player I've been toying with. It's been great fun and I plan on making a lot of songs.

Guitar Hero software: Freetar.
