i might have an idea, but i believe it's quite dumb and most likely you have already tried s.th. like what i'm going to propose...ah well, ok, here goes:(posted 8498 days ago)IF (mouse works in game A) AND NOT (mouse works in game B) THEN (hardware is o.k.)
...which implies the game settings are faulty we now try to answer the question 'how the §"$% do them there games differ?' :))
1st possibility: under mame (controller) options, you activated BOTH joy and mouse input - some games don't like that and you'll have to leave the joystick input out 2nd: previous in- game configuration (TAB) set to cursor keys and/or joystick axis explicitly overrules analog mouse input.
3rd: i totally misunderstood your problem, and the mouse works but you just can't get it calibrated - in that case i'm sorry but i don't have the slightest ;8
