For anyone else having this issue:

I'm still not sure what caused it. But I "fixed" it by downloading 4.2 and doing a fresh install.

Thank you for anwseri g steptoe!
I'm Sorry for that, but what's 5G?

I have a PS3 and of course controllers for it, but I like to use the "originals" shape of Controller for each emulator. For example the USB version of NES Controller for NES games and the USB version of N64 controller for N64 games.
There are Bluetooth versions of them too, but these are way more expensive than the USB ones. So my decision is to use the USB ones.

Just go for a PS3 controller. Now mind you, you need to plug in the PS3 controller via microUSB, then finding ps3controller on the RetroPie setup.

This should probably help you.

@theplayerone i have two of the raphnet adapters. They work great for me. Sorry you are having an issue with it.

@heinstein also, if you fix the first file you listed you wont have to configure any more configs

@oden55
The Raspberry Pi 3 has built in wireless so you can follow the directions here:

@Vliro If you disable the xpad driver in RetroPie you get the kernel xpad driver, which is the same between RetroPie and Raspbian (RetroPie images are Raspbian).

@obsidianspider I have read up on typical RPi3 BT speeds and they shape up to be maximum 256kb/s

Meaning that the BT Display would be 15551.5625 the maximum capability at best..... The compression would need to be 20,000x in under 10 milliseconds. That kind of compression would take hours to years for a Pi, and the entire screen would be an artifact.

@overfl0w Try this! It worked for me

@jabberwock101 yes i would still try this patch. I would say it is most likely to fix it.

I'm having a similar issue at the moment. I've been trying for some time to get Joust working (it's my all-time favorite video game on any platform!). I just recently figured out how to reset the game to get it to actually start up, but now I can only control it via the keyboard. My 8bitdo SNES30 controllers don't seem to register any button presses, but they work fine for all other MAME games. The behavior seems to be the same for lr-mame2003 and mame4all. Any ideas? I'm on the same hardware and software versions as the OP.

I have two different generic receivers, both of which work fine with RP. No need to spend more money on a genuine microsoft receiver :)

It worked! Thanks!

Hi, did you have any luck with getting the Steam controller to work?
