One piece of potentially helpful information i think you forgot is, what is your controller?

Hard to say, i’ve never used reWASD. There’s another program called Input Remapper that i haven’t used for games but which is supposed to be like AntiMicroX but for keyboard, mouse, and gamepad inputs and outputs going both ways. So i can make my keyboard an Xbox controller, my Wii U controller a keyboard, my mouse a pair of DK Bongos probably, and so on. But i don’t know how to make it work without sudo access (apparently some programs need that and some don’t to mess with inputs) so i don’t like using it.

Some people don’t like Steam running in the background. My last computer was so weak it couldn’t run light weight games through Steam because of the extra resource usage.

AntiMicroX for converting gamepad inputs to keyboard inputs. I pretty much only use it for Super Smash Flash 2.

No mention of M&M Kart or Super Bombad Racing⸮

Cemu isn’t the only game that breaks with this controller, and if i could just set right stick right to C stick right, i wouldn’t have ever noticed this issue for Cemu. I’ll bear this in mind though if every Linux build of every game i’m interested in playing announces support for DS4 though.

I’m using AntiMicroX. This doesn’t work though. Hollow Knight picks up on the controller pretty soon after it’s plugged in. Sounds like Steam Input will be my best option for now.

Probably deafult settings for Steam Input. I’ve had troubles with that breaking games before.

Seems like a good option. Thanks.
