Got RetroPie set up yesterday and everything seems to working fine in EmulationStation. I went through the retroarch config process and all the buttons were appropriately detected. I did use duplicate settings for L/R analogs and a couple buttons. However, when I boot a rom up in MAME, the entire controller is dead.
Has anyone successfully set up a Mayflash Arcade Stick who might be able to shoot me some pointers or tell me how to get it working?
