That allows it to know which direction the spinner is in wherever you stop the stick.

Yep, also the encoder disc was something like a 72 tooth disc, it happens to be the same as one of Oscar's models.  The game caclulated direction based off that, but used the calibration disc to help keep it calibrated.

I think you could easily make your own 720 stick and use analog mame.  You could do it with one disc instead of two also.
A due north on the encoder disc just cut two of the teeth deeper and place a second IR set deeper to sense the deeper cuts.

It would be cool if you could get an oscar spinner (or other brand name) with the exact disc size from 720 with the above modification.  Also have a spinner knob that can accept a joystick that you can place over and attach.  I've had an idea for this but don't have the funds to make a prototype.

I picked up a real DOT spinner awhile back, and have been toying with the idea of retrofitting my Oscar DOT spinner, to create a 720 controller.

I was looking to fit a second encoder wheel on it, but the "deeper tooth" idea has some real potential, I think.

Depends a lot on the analog stick (the POTs, the range of movement, and the driver).  

My old gravis analog stick plays pretty well if the springs are set to the lowest setting. Variable spring analog joy from 1991! (Need to recalibrate it once a day, though.)  
My gamepad analog stick, OTOH, sucks donkey; it is very diagonal unfriendly so going diagonal is very hard.  (Makes an okay 4-way in mame, though.)

One thing with all analog sticks is you don't have that feel of the original stick-spinner that you can't shortcut across the center.  (Unless you BYO to restrict it from doing so somehow.)

Thanks :)  I gave it a try last night and it played OK...but the restrictor is quite square, meaning that I didn't get the 'circular' feel I imagine the real controller would have.  It felt pretty good considering, but the square-ness was not good.

Actually, I did have one problem in 720 with MAME Analog+: When I launched the game all would work OK...then I would play for a while, and after a seemingly random amount of time, the joystick input would just stop working.  I thought it could be my hardware at fault, but if I went into Analog Settings, I could re-map the joystick inputs no problem.  But then back in game they would not work.  If I quit MAME Analog+ and then tried again, same thing (work for a while, then not).  Not 100% sure if it is a bug or something with my system...I was using v0.83 btw.
