Problem with the Classic Controller setup and N64 games

[Terg500]

For some reason whenever I press L1/L2 or R1/R2 on my PS4 controller the Z button always activates with the L/R buttons. So for example in SM64 while pressing the L buttons a long jump is working fine since the L button isn't used in the game but with the R buttons Mario ducks and the Mario cam gets activated at the same time.

I don't know what I've set wrong, below is an image of my Classic Controller setup. The controller itself is being detected as a XBox controller by DS4Windows.

If you also have an emulated GameCube controller configured, try disabling either the GameCube controller or the Classic Controller. The game might be reading inputs from both at the same time.

Oh thanks, that was indeed the problem.
