Emulator Problem: All-Purpose Gamepad

Hi there!

I have previously searched for a all-purpose gamepad to find nothing.
What I mean by "all-purpose" would be something that had enough button for a
Nintendo 64/GameCube emulator, but can also comfortably work with things like PlayStation, GameBoy, etc.
I haven't been able to find anything yet, but figured that I could ask around.

Thanks in advanced!

There are a lot of ways to do this. Though like everything its not what everyone agrees on.

1) A universal adapter (requires old controllers) http://4-play.bliss-box.net
2) a 360 pad, I don't agree but most everyone does this that I know of.
3) a psx/n64 adapter. Requires the OEM controllers. The two patterns work for just about everything.
4) a PC game pad like gravis made. Or the 3dfx hammer head, one of the best.

Thank you! Sorry for the late thanks, things have recently been very hectic
I'll look in to this as soon as I've got some free time!
