Very slick looking tron joystick. I really like how the threaded shaft allowed for the wires to run through the bottom so you didn't have to do the usual headphone jack coming out of the joystick like those other guys who have done that do, I think MameGtx did that as well... can't remember.
I think I got my raider blue pro for like 11.99 at best buy, and I tried it out, and by itself with drivers installed it actually works with Mame, but I'm really afraid of breaking the joystick shaft because it's made of plastic, very cheap plastic. One cool thing about it is that it works in most first person shooters, so if you've got a trackball *I did this for a bit* and a raider blue pro next to each other, and want some The Grid style fps action, joystick/trackball is WAYY fun.
-Good job on the tron hack, definitely post pictures when you get that led in there and running!
