I don't think you can on the -deck builds. There's asus builds with lots of asus specific tools including armoury crate features, but those are desktop builds (they're meant for the asus laptops and 2-in-1's, not the ally x). For the Ally X there's HHD for controller mappings, and through steam input.
Sorry I’m a little confused as to why you mentioned deck stuff, I don’t have a steam deck nor a desktop. I just have a rog ally x and wondering how I can reprogram the joysticks
I bought the hall effects joysticks and installed them on my rog ally x. I had to open up the rog ally x and everything but I have to reprogram the joysticks.
The rog ally x has windows installed with armory crate and I can use armory crate to reprogram the joysticks, but with bazzite there is no armory crate to use. So I’m wondering if there is another app or something that I can use or if I need to reinstall windows.
