@garrisonhale670 said in 8.0.1 vs 8.1 - can't hide preinstalled games anymore and unknown disk usage:

Hi! The USB guns that came with my Arcade Guys cabinet are what I'm using. I can move the cursor around, but I can't get the cannons to fire. Is the mapping done in the Tetrarch settings or in the Recalbox controller setup? I am unable to mapping the gun start or gun choose buttons to any of the gun buttons in Retroarch settings; instead, it displays "mouse 1" next to the gun start button?

I solved my problem with the help of my friend.

@zing Thank you very much.
I try factory reset ...
