i'm new- question about controller

i'm new to the emulators- honestly all i really want to do is play original tetris... i'm on a mac running osx. 10.4- can i buy just any usb game controller, and use it with the tetris rom?

sorry if this is a stupid or obvious question...

thanks for your time.

It's not a stupid question.
On windows you can use almost any game controller for emulators I don't know a reason why it shouldn't work on a Mac.If you have a friend that has one try it.

right on... thanks so much. i think i'll go pick one up tonight and give it a shot.
