Anyone know of a way to hook up a super nintendo remote to a USB and have it work on the computer?

I have some roms and want to know if i could make a usb super nintendo remote. Any ideas? Hopefully that won't cost an arm and leg.

You need to buy or build an adapter like this:

I've seen those for even cheaper in bargain bins at game shops.

There are plenty of builds on the web, simply google SNES + USB and browse around.  Building it yourself is most likely going to cost you much more than $10, but you'll have the satisfaction that only a home made object can give.
