I increased Mame's sensivity to about 300%... still no effect at all....
also... I tried their new driver, mouse acceleration/speed... and others...
but still.... its speed is NOWHERE CLOSE to a playable speed...
For Arknoid, I need to go from 1 edge to the other quickly at times... and I'll need about 3-4 complete turns before I can get there..... (that's after speeding up everything....)
and I don't get help from their support about this....
so... I returned...
-------------
ps: I read thru. their docs... somehow, in the MAC version, it seems like they have an option for you to check to make it a spinner control for games.....
(but they do not have it for the Windows Verision....

)
so.... I returned it before I got stuck with it.....
