Hi

yes, I didn' look in detail how TOS handles mouse movements, but 
intercepting absolute and/or relative coordinates from the ikbd might 
give some good results (fine tuning might be necessary in all cases to 
get the correct sync /speed up)

To get proper acceleration under everyone's PC, myabe we would need some 
SDL calls to get the current global screen resolution as well as the 
size of the hatari window (this one we have already). The ratio between 
desktop X/Y res and hatari X/Y size should be used to adapt the speed up 
/ sync.
