Auto config question

Hello, I’m using the Desmume 1.3.4 core in RetroArch and the issue i’m having is that the emulator is auto-binding one of my controller buttons to the Lid Open/Close key to my L button on my controller so every time I press this button on my controller the game locks and turns white until I re-press the key again and I can’t seem to disable it at all, and there are no other buttons I can use in place of it as the DS and SNES controller layout uses the same amount of buttons I think. I’m using an SNES controller with the RetroLink USB adapter. Is there anyway to unmap the auto key config for this function?

You can’t unmap it but you can go into the core input remapping (‘controls’ in the quick menu) and change that function from L1 to something you don’t have, like L3.
