FYI and to add information to Kremmit and u_rebelscum's post,
DOT does not use quadrature and looks to be 1x from the schematic. So, even though it has the second largest tooth count, one should be able to play this "arcade accurate" with a 32 tooth encoder using a standard optical interface, i.e. mouse, opti-pac, opti-wiz.
A 36 tooth encoder seems to be the magic number for the 72 tooth encoders, Atari, etc IF all they did was 1x and 2x.
I doubt Arkanoid is using anything more then 1x on it's 486 tooth count.
You just dont get it...
Mame is most likely set up in such a way as to REDUCE counts. To compensate for the new
Optic counts of today. Otherwise, they inputs would be too powerfull and Nothing would control right.
(backspin on every game)
Also, you are basically saying that if you had your choice to have 32 precise steps to go from
point A to point B.. youd rather take 5 monster leaps! That is a Lack of control!
Quite simply, while you CAN get away with less encoder teeth by adjusting mames settings...
it will be like taking 5 steps at a time rather than one at a time. This creates a 'jumpy' effect. Its not
as precise. Even if its not visible, it will be effectively causing a loss of control.
Its BETTER to use a very high number of teeth, and Lower mames settings. In that way, you are
matching the games imput precisely. You will get a much finer ability to control the characters in
most games. The characters will move smoother too.
This isnt opinion, its Fact. More teeth = finer control.
Btw, Why do you think it uses 1X? Because that gives even more count to add up. Thats one
step at a time.. rahter than 10 steps per click. This translates to serious amount of control range.
Notice that on DOT, the spinner runs the Pointer in a HUGE ring arround all sides of the Play-Box. Thats a lot of ground to cover.. and yet to hit Sark at such a distance, you need very good precision.
If you are content with your pointer skipping every 5th pixel, or having to turn the knob 3times more than should be needed.. then thats your perogative.
And Timoe, you may be right.. as IF I could get a product in place, it just might be the best...
because I wouldnt cut corners and put gameplay control functionality "underneath"
a few dollars more in costs. Of Course, not everyone cares about the best.. they may desire
less footprint, lower cost..etc. Still, if one is educated in what makes something better,
it may in fact drive things in a better direction. Esp with all the competetion

My comments are not complaint slams.. they are a mere revealing of the truths. Oppurtunity for improovement, and suggestions for it. Its called Constructive Criticism.
Let me give the positives so as not to seem 98% negative:
- The only DOT spinner in production
- Spins smoother and longer than the original (less friction in the design)
- Great Knob! Best one available acutally. (imop)
- Built Very durrable. (with exception to the switches)
