A Game (AER) recognizes xBox Controller but not 8BitDo Controller

I have a controller from 8BitDo which works fine in all games besides AER. Even though it does work with an old wired xBox controller.

Has something similar happened to anyone?

which 8bitdo controller? many of them only work in Switch mode by default

nursing-lime•3/21/25, 9:32 PM

if you can get it to run in xinput, that'll probably make it detectable by the game

conventional-blackOP•3/21/25, 9:54 PM

Ultimate 2C. Cant find an option for Switch mode :/

conventional-blackOP•3/21/25, 9:56 PM

For the Game Hue both controllers don't work. Haven't tried that until now

nursing-lime•3/21/25, 10:04 PM

are you using the 2.4GHz dongle or bluetooth with the Ultimate 2C?

nursing-lime•3/21/25, 10:04 PM

2.4 mode will use xinput

nursing-lime•3/21/25, 10:05 PM

while I believe the bt mode uses dinput to look like a PS4 controller

conventional-blackOP•3/21/25, 10:13 PM

I tried Bluetooth, 2.4hz dongle and usb cable.

btw GTA and Rocket League work just fine

conventional-blackOP•3/21/25, 10:48 PM

rly confusing

conventional-blackOP•3/21/25, 10:50 PM

it might be a proton problem - not heroic related tbh

broad-emerald•3/21/25, 11:16 PM

Heroic doesn't have anything to do with it. Besides supporting controllers within its own interface, it doesn't do anything with them.

nursing-lime•3/21/25, 11:43 PM

more of a game problem than Proton

nursing-lime•3/21/25, 11:44 PM

Steam input can interface with controllers, and Proton might provide some backup in that area, but for non-Steam stuff it's up to the game for proper support

Yeah, some games have trouble with (some) non-Xbox controllers, even when they masquerade is Xinput devices. I had that problem using a Sixaxis controller with Ys VIII.

nursing-lime•3/22/25, 12:00 AM

sixaxis is probably going in as dinput

broad-emerald•3/22/25, 12:24 AM

Oh, I was using whatsit at the time. xboxdrvxboxdrv.

tbh all my 8bitdo controllers work fine in xinput mode

dry-scarlet•3/22/25, 8:50 AM

granted those 2Cs are so new

broad-emerald•3/22/25, 10:26 AM

For what it's worth the manual for the Ultimate 2C doesn't mention operating modes, unlike every other model I've used. I don't know what that implies.

So i found out:
Bluetooth will use dinput
For wired or 2.4 GHz one may change the Mode to xinput by holding x while restarting the controller.

However AER is still not working (either d- or x-input)
I noticed another game not working (Hue) - here I can see a bit more than in AER.
Somehow L-Stick works. R-Stick not.
A-Button is recognized as "Positive Button 0"
B-Button is "Positive Button 1"
X -> 2 and Y -> 3

I was actually interested in buying a 2C, but if their xinput support is buggy, then that’s a hard pass :/
(that you apparently also need one 2.4GHz dongle per controller is not great, either…)

dry-scarlet•3/23/25, 8:25 PM

its interesting older 8bitdo's work fine with aer, my gulikit also

dry-scarlet•3/23/25, 8:29 PM

you can use jstest to check your controller inputs in a terminal (you'll likely need a full screen terminal to see it correctly)

worthy-azure•3/24/25, 1:30 AM

It seems to specifically be the 2C people are having trouble with. This is like the third post I've seen from someone with a 2C saying it's not working in a situation where it reasonably should
