Space issues perhaps?

I note that vnman uses AA's in his picture advising on Joystick location here:

Hi Guys, Currently on my first build and awaiting parts... So reading up and prepping nas much as possible. One concern is around safe shutdown of the Zero, specifically if using an AIO without a Teensy, e.g. the new Helder 2.2 Is this still an issue with the new AIOs? I guess my question is....can ...

What controller is it? From experience, this can sometimes be down to the joypad driver selected within the RetroArch config.

Especially for Bluetooth controllers.

They work fine within EmulationStation but if the driver is wrong some or none of the buttons work within the games.
