Where can you play UN squadron on PC

You can download a super Nintendo emulator and then download the game and play it on your PC. The best thing about doing this is that there's an emulator for just about every game system (all the way up to PlayStation, that i know of) and you can find almost any game that you can think of doing this. The best emulators that i know of are:
Nintendo --------- Nestopia
Super Nintendo - ZSNES
Nintendo 64 ----- Project 64

There are more emulators out there and tons of games (roms) , you just have to find them. You can go to http:/www.romnation.net They have a lot of roms and emulators.

Hope this helps you
(by the way, UN Squadron, AWESOME GAME!!!!)
