Nice project! Which controller models have you actually tested on real hardware?
Thank you! :)
I've personally tested every PS5 controller variant: the DualSense, the DualSense Edge and the PlayStation Access controller, plus the PS4 DualShock 4.
Other people have used InputConfig with GameSir, 8BitDo and a bunch of other brands with success, and Xbox and Switch Pro controllers work through macOS's own controller support. I've also had a lot of random controller success stories which is so cool:
