I was going to post this in /c/retropie but it seems they haven’t had any activity in 8 months. So I figure here is the next most appropriate place.
I recently brought out my raspberry pi, and started taking care with it. I downloaded some new themes. I put a hell of a lot more roms into it.
One problem is, if I try to connect a controller, I can map every button except LT and RT.
At first I thought it was because I was using the 8 Bitdo Switch arcade stick (which also has the ability to connect to PC/Linux/Raspberry Pi.
I didn’t understand it, but I thought "Ok. Maybe something about it being an arcade stick means I can’t use those two buttons on THIS stick. Whatever. I’ll just use a different controller.
So I pull out my WiiU Pro Controller…SAME EXACT ISSUE.
So now I don’t know WHAT to think. I WAS going to connect it to my switch, and see if I could do a button test on that, to see if it registers the inputs for those two buttons, but now I’m not sure that’s needed if it’s had the same issue with two unrelated controllers with two different form factors, made by two different companies.
Is this a common issue with an easy fix, or has life once again said “FUCK YOU Lost_My_Mind!!!” ?
I’ve never had issues with the 8bitdo Controllers on rpi, Bluetooth or wired, but I found a thread where others solved the same problem. Looks like that particular controller isn’t perfectly supported and you need to update xpad and a configuration file.
I’m running RetroPie on a Debian laptop and I’m able to map all the buttons of my 8BitDo Pro 2 controller; no issues at all. I was also able to connect and configure an Xbox 360 controller just fine.
You might want to try getting help on the RetroPie forums if you don’t get any luck here.
Two questions:
Are you connecting via USB or Bluetooth?
Do you have a toggle anywhere to put the device into XInput mode?
Bluetooth, and I’ll check again when I get home, but I’m almost certain it was already on x-Input.
I suspect it’s the latter because with my (chinese knock off) xbox360 controller I can map all of them.
What if you install retropie or mame on your pc and try to map it here? Maybe it’s a driver issue
