Game on the left

[tavernylol2 tavernylol]

Hi everybody! First of all i want to thanks devellopers and communities for their work on this super project.
I just began with recalbox on my raspberry 3 , during a game (mario kart on super nintendo) i hazardously misclick with my xbox controller, it place the game on the left of my screen and this appened for every game with the same video format.
I searched on the web, but the only personne which had the same probleme, didn't had any response.
So you are my only hope General Kanobi!
Thanks !!

@tavernylol2-tavernylol i'd remove the mupen64 folder in share\system\configs, reboot, and try again
