I’ve been playing some older console FPS games lately and my aim with sticks is beyond rusty after not aiming with a pad in over a decade.
On the Windows side some people have made “mouse injectors” like KAMI and MouseInjectorDolphinDuck.
Rather than just binding the right stick to mouse inputs (which I have tried and it feels awful when it even works at all). It injects into the game/emulator directly to mimic mouse look as close as possible to a native PC titles.
Can’t seem to find any similar projects being worked on for Linux? Or am I just blind a missing something obvious again?
KAMI has some Linux build stuff in the repo but according to the dev it’s “Just some scaffolding” and not actually supported.
Edit: fixed spelling
For non-Steam stuff, sc-controller might do the trick. The Dolphin and Duckstation forks are Windows only (yet uses manymouse which was for Linux). You could try your luck and see if they work in wine/proton as backwards as that sounds, just use the OpenGL/Vulkan renderers and hope for the best.
