Please add some more info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

I assume that by 'not detected', you mean you can't configure it in EmulationStation ? Can you try to test the gamepad with jstest (see here and see if it works ?
Please post the result of the following commands:

cat /proc/bus/input/devices lsusb

@Addison No Problem :-)

@Thorr69 Yeah, DUH on me. I saw XBox and then put my bliinders on! MY bad!

@mitu I can confirm that works. Thank you!

@mitu
Thanks for the reply!
I do have a normal TV, the problem is that the HDMI cables I've ordered along with the pi 4 don't work. I'll have to order new ones to test at a later date.
The reason I just kept working on with this screen was that I wanted to build a small (4:3) bar top arcade with it.
Now, knowing that this screen won't work for this, I'll have to research for a suitable replacement as well.
Thanks for the help :)

​Solved. Bad VGA cable.

If the controller is plugged in with a cord it will detect it, but it will not detect the 8bitdo adapter. I didn't install a heat sink on the internal Bluetooth chip because I had this adapter and planned to use it. I don't know why it can't be detected.

This happened to a lot of people with the new PI4 model - thinking they can re-use the miniHDMI cables they had for the Pi Zero.

If your Xbox One controller supports Bluetooth, you don't need a wireless adapter. I think newer models (after 1708 ?) have Bluetooth by default, but you can check your controller model for BT support.

@blackholebomb
I had to add usbhid.quirks=0xf000:0x0008:0x100000 to /boot/cmdline.txt and then reboot to get the missing buttons working.

@traptedmind - Thank you for posting this! The googledrive link appears to require access. Can you post the contents of the .cfg file to the thread?

Thank you!

I also wrote this once:

If you wanted to compare. :)

@crafunzio Sorry, I dont think i have a hdmi to rf modulator. Mines a rca / av to coax. I used the pi`s 3.5 jack with a AV cable into the modulator. But you'll find hdmi to coax RF modulators on ebay / aliexpress etc for ca 10 bucks.

(But i would def recommend paying a bit extra for a pi2scart or similar if you have a european / scart crt set.)

Did you try @meleu's joystick-selection tool?

Saving the config in the RGUI

That's not how it should be done - you should (have) use(d) the Core Remapping option in the RGUI - https://retropie.org.uk/docs/RetroArch-Configuration/#core-input-remapping.

I guess I must have completely missed that option somehow. That's worked perfectly - thanks so much for pointing me in the right direction :)

Check this out and you can get even 4 Atari joysticks connected with a single USB. Works great with my Raspberry Pi 4 and emulation station. https://www.icode.com/atari-joystick-usb-adapter-design/

Thank you for the replies everyone. I am probably going to go for the two port Mayflash adapter. The Raphnet stuff does look higher quality to be sure, but it's also double the price and on back order.

@ulao

Very nice. It looks like the Bliss-Box is shaping up to be the de facto adapter solution.
