[SOLVED] Steam Link In Retropie Issues

[KN4THX]

I used steam link on the Pi 4 while I used my Pi 3B+ a while back. A few months agao I decided to install the latest image of Retropie on my Pi 4 since I saw good results with steam link and wanted to hve everything on my Pi4 and retire my Pi 3B for some other projects. I have two issues, one of which is keeping me from troubleshooting the original issue. I know this is n experimental package so I do not expect a solution but wanted to try.

1. I launch Steam Link from ports and it goes to either a black screen with a mouse cursor or black screen with a steam logo and just sits there. The Pi 4 isn't frozen, I can SSH in and do everything as normal, it just appears to be the port itself.

2. I have an 8bitdo controller (SNES Pro) which I have used for several months on both the Pi 4 and 3B+ with no issue but originally Steam Link would not recognize the controller existed. I am curious if it is the pair mode I used, but cannot get to this point any further due to the unresponsive screen.

To troubleshoot the controller issue I had remved Steam Link and reinstalled it and that is where it went from launching the application to only getting to a black screen. I had also originally installed it outside of Retropie to test it in a standalone environment so I am not sure if that added dependencies that the Retropie image is not liking but I am not sure how to check or remove any dependencies if that is the case.

Pi 4
2 8 bit do controllers - SNES Pro
Latest version of Retropie - Have upgraded multiple times recently both OS and Retropie.
External SSD for Retropie folder
Official power supply

EDIT:
Confirmed my Android phone can connect to Steamlink on my PC with no issues
Made sure I wasn't in BETA
Reinstalled Steam on PC
Confirmed I can strem from PC to Laptop so appears to be something with my Pi installation.

EDIT 2:

Had to delete this directory and reinstall Steamlink

~/.local/share/SteamLink

On the controller side of things, two pair methods work for Retropie perfectly but Steamlink needed D-Input apparently (which I found out by searching on here now that I could get that far).

Solved and thanks!
