if you have mapped to keyboard, you will have to either change it so one is mapped to enter, or just use a small wireless keyboard for configuring etc.
I may stick with using your xboxdrv guide for this task since it's already part of Retropie. Getting joymap compiled and configured might prove to be a huge headache.
@mediamogul you are correct about my joysticks Axis... the only hope I am holding on to, is when the mode button is enabled, my Dpad values go from hat #0/#1 to axis 4&5/6&7... My end game is two have two players on mupeb64plus. Thanks for the replies guys!
@CHRISCaPWN That post is clearly linked on registration and you are asked to agree to it. Without details of your set-up it's impossible to advise on this. It also states to open a new topic when asking for help (providing the information requested), so please do that.
