So I managed to install RetroPie (Ubuntu) on Mariko (SX Core, if that's relevant). The problem I have is that I can't configure the gamepad on emulation station. When I map certain buttons, the OS commands take over. Like for example, I wanted to map + into START, but it instead bring up the keyboard, or - with SELECT but instead rotates the screen.
Is there anything that I need to know in order to successfully install this?
