@Zing Thank you. But actually I found out that using a different emulator I can configure it better using the key button + B, and after remapping my joystick from scratch it fixed the problem and I can play Super Mario 64 perfectly using the other emulator from libretro. The only thing that is not that nice is the size of the menu, the font size is too big and sometimes it is hard to read the menu options because the text overflows the available space in the screen.
