​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.

@TraptedMind Works fine on PC! I was able to play all my games. I used openEmu on Mac.

I also wrote this once: https://retropie.org.uk/forum/topic/12836/guide-how-to-n64-controller-setup-with-micro-s-n64-pcb-converter-and-mayflash-usb-adapter If you wanted to compare. :)

I went with this one , had free shipping. Will post when tried out.

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

@mitu said in Flipped Buttons on DualShock2 with Adapter: @IonicOwl said in Flipped Buttons on DualShock2 with Adapter: 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.

If this helps you, then I looked at the review on this site. There are other adapters there, but I'm not sure about them. https://www.bestadvisor.com/bluetooth-adapters

@deeobat the manufacturer confirmed that the cable is not compatible with Retropie. Oh well.

It's hard to say if you have the proper power supply. Maybe check your power cable. I use an extra long one and keep that in mind when I am troubleshooting. Maybe your Pi or new power supply is malfunctioning. Do you have a second Pi to test your current card? Since it's global it sounds like you might need to do some additional troubleshooting. I would almost reinstall with a fresh image on the SD card (or a different one) to rule out the SD card, image & configuration. Maybe a different USB drive if that's what you're using. It seems there's a lot that could happening to make a determination or if it was a larger/build related issue more would be posting.

It's variable, and I'm still working through them one by one, but yes. I don't really want to overclock, but Mario 64, Diddy Kong Racing, Mario Kart & Starfox work pretty well. I still have the original console, so although they're not perfect, those ones are pretty decent. Goldeneye & Perfect Dark seem to need more power to run well. Conker's Bad Fur Day is unplayable. Working on F-Zero X & Wave Race, as I've read they should work without an overclock, but aren't brilliant on mine. Why do you ask? Rob
