Hi,
First of all, sorry if this is not the proper place to start this topic:
I managed to successfully install Arch-based linux distro Groovyarcade and the Groovymame ver. that comes with it (GroovyArcade-Arch2015.02.15-x86_64.iso). I set up the whole thing to use it with a vertical monitor (a rotated scart TV actually).
I enabled the mouse just to play arkanoid-like games and at this pont is where I meet the issue. Indeed any optical mouse I plug in is recognised but sometimes, when you are moving left and right for example the vaus capsule in arkanoid, it sometimes gets stuck unexpectedly in the middle of the screen. Other times you just can only operate the capsule in the left half of the screen, next ball play only in the right half etc.
I´ve tried to only plug in a single mouse device in case there might be some kind of conflict, no joystick either. Any other attempts like disabling light gun support in mame.ini bring the same dismal results. I´ve ruled out a hardware failure because any mouse/spinner works smoothly and flawlessly in LXDE Desktop.
Any ideas? Help is much apreciated,
Thanks in advance,
