btw, these have been out for a while... and nobody seems to say good things about them with mame.... Because the calibration maybe...
Try this. Force mame to run at the same exact resolution and refresh as Virtual Cop (or whatever) and calibrate it in VC... then run mame.
OR... make it so mame CANT change resoluitons and try to do the same with VC.
This might do it..
btw, does it work like a mouse? or a joystick?
