I bought a couple of these for some Retropie setups I'm building for family Christmas gifts. I opened a couple of these and on both controllers the trigger buttons weren't recognized in the controller settings (button pressed all day on the button mapping screen and nothing). All other buttons are recognized and working correctly except R2 and L2. I opened up the controller and found that they appear to be working (the guts are there and it looks like they should work). I bought them because they say they work with Retropie, but there seems to be some inconsistency. As the other buttons work fine and Link seems happy with the N64 Zelda games I'm leaving these and I haven't researched them thoroughly enough to say if the controller is to blame or if the retropie setup doesn't recognize or die show buttons. .
