@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.

@burts_19 I would like to know the same.
I have a raspberry pi 3 - B model running Recalbox 6.1.1-DragonBlaze, a Xbox One wireless controlled paired and configured in the os main menu.
When trying to run a N64 ROM, like Mario 64 I have noticed that the button mapping does not fit my needs and also the sticks deadzone are not ok, when trying to bring up the emulator menu by pressing "select + B" nothing happens.
I look for such configuration tutorial in the wiki and forum but could not find it.
