@acris Sorry, is there really no way to solve the problem? I have also reported the bug on github, but no one has deigned to answer, even if only to say: ok let's check or let you know or something.
@olivierdroid92 Thanks. I already remap on retroarch menu. But A, R button of 2P is not working.
My favorite board is x64. I want to play tekken tag with my friend. tekken tag is possible playing in mame2010.
A, R button of 2P is not not working also on RP3, RP3+, X64 all board with all game pad, gpio too.
@rizzie Dude, don't forget the system runs on a computer!
On a regular computer, you don't power off without shutting down properly, do you ? That's the same thing with Recalbox: you must shut it down properly before powering off your game machine.
