@Substring Hello, great job ! it works pretty well (I'm on the pi version).

However, I have some issues with the 8 bitdo sfc 30 pro controller:

• Test on the n64 zelda oot when I press the trigger L2 (maps as z on the n64 controller ) it acted as if I was leaning on it, no way to remove the aim.

• When I press the hotkey, it changes the shader (as if I was doing the combination hotkey + L2)

• In doom when I press the trigger R2 he alternates between bare hand and weapon which makes the game impossible to play

• That's not a problem but to activate my controller in game, I have to press L2+R2 otherwise my controller is not working.

• In the menu retroarche, I have big difficulties to move to choose an option.

Test with an Xbox 360 wired controller and I did not have any of those problems.

• Then on ES I sometimes have black screen completely random but rare enough to not deteriorate my gaming experience.

For the moment that's all my feedback that I have to share

Thanks.
