I wasn't aware of the existence of a dual mouse driver, and since I'm already using Advmame, it was no sweat just adding the following lines to the RC file, and works perfect.
Rampy, if you can't get rid of the stuttering w/ the dual mouse drivers, just add the following lines to the advmame.rc file:
input_map[0,trakx] mouse[0,0] mouse[1,0]
input_map[0,traky] mouse[0,1] mouse[1,1]
Just FYI, the '0' in the first set of brackets is declaring the player # (0 is player 1, 1 is player 2, etc..), in the rest of the brackets, the first # in the bracket declares the device, the second # declares the axis. You don't really need to know this to just cut-n-paste the above lines into your rc file, though!

There are thousands of options for the .rc, all located in advmame.txt in the DOC (or DOCS) folder in the mame directory. You should spend a lot of time sifting through there for cool stuff!

I also have a script in there that gets rid of the OK and other mame intro screens, for instance.
