[Solved] 8Bitdo Issue @ game launch

Luke_O

So I've been putting together a new Retropie build for a friend and been setting up 2 8Bitdo controllers for him. After working through some connection issues between the controllers and the Pi I got everything to stay connected (and reconnect with no issues) and mapped the controllers. When first trying to test them out I launched a random rom and the system seems to freeze on the retroarch/libretro screen (may be the wrong name). I thought something had frozen so I had to do a hard power down and restarted the system to try again, same thing happened. This time though I shut down the controller first and as soon as the controller disconnected the game launched... I turned the controller back on, it connected with no issues, and I was able to play the game. I went through this process several times, with various games across several different emulators (megadrive, nes, snes, etc.) and the same thing happened, system would freeze with the controller on. It didn't matter how long I waited, as soon as I turn the controlled off the game will launch. Not really sure how to fix this, any suggestions?

Setup:
RPI ZeroW
Retropie v4.4 - Ran all the updates for Retropie and the underlying Debian OS
8Bitdo SNE30 - updated to Firmware v6.1 - udev rule was setup through config screen.

You shouldn't be needing the udev rule if you're on a recent firmware. It looks like the runcommand is stuck before launching the emulator.
Can you try disabling the launch menu in runcommand from RetroPie-Setup as explained here and see if you get the same problem ?

I tried to turn off the launch menu but when launching a game it just get stuck on a blank screen now. Again tried this for various amounts of time and same thing every time, as soon as my controller is turned off the game launches.

As far as the Udev rule, I thought this was still needed, I thought it was only the 'mapping hack' that wasn't needed on later firmware? Could the udev rule be causing an issue?

Could the udev rule be causing an issue?

I don't think so, but if it works without it, I don't see the point in adding it - it was meant only for certaing firmware versions where the controller wasn't properly detected as a gamepad.

@mitu either way I went and deleted the udev rule and no change... At this point I'm going g to completely remove the controllers and the config files and run back though the setup process. If doesn't work I'll completely wipe the SD card and redo everything.

I'll post back with any updates

I finally got these controllers working after completely wiping my SD card and rewriting the Retropie image. The only difference this time is that when running through the update I didn't update the underlying kernel, only the Retropie packages. The only reason I did this was on the previous setup this caused several issues such as having to log in at power-on. These were easy to fix but I didn't feel like dealing with it.
