I think some people are having input issues and some games might not have the incorrect orientation. But, I'm using a 360 controller that seems to be working.
This is directly from the forums.
Yesterday I recevied my new RPi3, I installed Retropie and compile lr-mame2010 since has the higher supported romset. Everything seems top be working, I am able to load multiple “heavy” roms but the controller seems to keep the buttons pressed after pressing them once.
I tried with a (fake) Xbox 360 controller and also with a standard keyboard.
Does anyone had this problem? When I press TAB button to get the menu, after pushing DOWN or UP the highlighter option keeps cycling.
Any help will be appreciated.
