About a month ago I found this really freaking huge joystick at my local GameStop.
It is an unlicensed Super Nintendo controller that is made from a real arcade stick and buttons. All the other things that I have been talking about were made for home but this was made from parts of the real thing. They were selling it for 5 bucks and this probably went for a hundred when it was new. It is really big and tall but it really is fun to play. If I had a work shed I would make areal arcade cabinet with a SNES inside and this thing as the controls.
I wish I could get one of these babies for the Playstation.
Games that benefit from this: Street Fighter 2 and Mortal Kombat 2.. duh...
These things are super rare and I have never seen one on Ebay or at any other stores so good luck at getting one. But I GOT MINE HAHA!

I just wrapped one of these up on eBay! There's a tad bit of fading on the lower letters, ended up being about $30 or so after shipping because of the weight.
I have 2 of these, but I've rewired them to work on PS and Saturn. You just need a controller to take the guts out of and put into the joystick. The one I made for the Saturn works with an adaptor on the Dreamcast, but for some reason no longer works on the Saturn...
I have one of those. Its not a bad controller I actually was able to network it to my PC with a Smartjoy Adapter. Sweet.
Yay! I just found one of these at a flea market for $5 too. Can't wait to try it out!
