I’m having a heck of a time to get things right with my two new ArcadeGuns and mame with Area51. After a whole day of just tinkering and troubleshooting I found that if I set the input to Raw I can get one of the guns to track with the cursor/crosshair on screen.
BUT, the cursor in the game (Area51 or any other mame game)is jumpy and erratic compared to the movement of the mouse on the desktop or in the retroarch UI. It seems like the movements of the cursor is super sensitive during gameplay.
I was able to configure the guns on Mame64 and it works great and the tracking is smooth. I noticed the resolution of the games in Mame64 vs the mame core in libretro looks different. Pressing the tab to get the mame menu on each look totally different. Could it be that the mame core operates at a lower resolution causing the mouse sensitivity? Am I on the right track? Any suggestions?
