retro controller wanted for my xbox!

[RCduck7]

I believe there are saturn, neo geo, snes controllers, street fighter controllers,... for the PS2.
So, they must be available for xbox to right?
Tried searching ebay for the keyword "saturn xbox" and "neo geo xbox" but no results with that.
Does anyone know or recommend a retro controller that is made to function with xbox and uses all of it's xbox buttons?

You can always purchase a PS2-to-whatever controller adapter.

I have one for converting a PS2 controlelr to either USB, Gamecube, or X-box.

I've so far only tested it with Gamecube, and it worked without difficulty.

The company that made that adapter I use is, "Mayflash".

I bought 2 or 3 SFII pads pretty cheap for Xbox.

I haven't tested them out well enugh yet, but they seem to be the best I've found.

I have an idea for you! Ok, first you buy a ps2 to xbox converter. THEN, buy the classic controller to ps2 converter. Plug in your insane creation and enjoy yourself

Enjoy it along with the massive lag.

I'll have a go at one of the street fighter pads.
Some say there good and others say there flimsy and only worth sitting in a collection.
Will order this now and see how that turns out.

Thanks.
