Hi, I just acquired a retro link N64 shaped controller, however when I try to configure it in ES interface I cannot find a way to assign C-buttons correctly since the mapping in ES is asking me for right analog. I tried mapping C button UP as Right Analog UP and C button Left as Right Analog Left but is not working when I play a N64 game. Actually it begins behaving strange because when I press left on my Joystick it seems to trigger the "C button Left". Does any one have any idea how can this be done? (I'm using mupen64plus with libretro). Thank you so much! 🙂
