Help needed: Building a PSX Spinner

[DumpsterKeeper]

I've built a couple of Beatmania IIDX controllers (The game is for the Playstation, Playstation II, and various PC simulators) but I need to build the turntable.  For those not familiar with the game, the turntable is basically just a spinner with a giantic disc attached to the top of it (instead of a little knob).

I've tried some of the Mouse hack links on the site, but they don't work for whatever reason.  Does anyone have any suggestions/links on building a spinner that would be compatible with a Playstation?  I bought a few PSX Trackballs, snipped one of the axises off, wired it up to my controller but it doesn't work.

Thanks for any help, it's greatly appreciated so I can stop using a pushbutton for my turntable.


Edit - Added a picture of the keys on my "compact model"  (I also built a gigantic 1'X2' one that doesn't exactly fit too comfortably on my desktop

I think you would need to hack it into a controller that's can already control the game. It would be way easier to build it for a pc port.

Didn't the playstation have a mouse you could buy?  Don't know where you'd find one of those... or whether it'd be nice to hack or not....

Playstation games don't just have mouse drivers in them though. There's only about three games that I can think of right now that supported the mouse.

Ahh... Dremcast was wonderful about controller compatibility I love my Dreamcast. They even made a joystick/trackball controller, I couldn't stand it though.

See if the game recognises the paddle built by namco.

Do any of the game system paddles turn 360 degrees?  IIRC my brother's NES Arkanoid paddle didn't.
