Retro Moonlight

Does this solve anything that RetroPie's built in scriptmodule doesn't already (https://retropie.org.uk/forum/topic/19872/moonlight-request-for-comments-and-testing)?

@simpleethat I didn't think I could, but I just had to ask. Thanks for the reply! :)

There was a thread about this in 2018, but I don't know if the two methods described there by @herb_fargus are still working.

For my part, I gave up on this and use an hdmi splitter and vga converter instead now to put the picture of my arcade cabinet on my video projector when I throw a party at my place.

Small supplement:

I updated steam-link with the experimental packages. Before, I added the PR from @psyke83 in scriptmodules/ports/steamlink.sh.

Now, I was able to play the dolphin-emulator mith my xbox-360 controller:

I opened steam on the host-pc I started steam-link in retropie I switched on Settings/Streaming/Advanced Options/Start Streaming desktop and then I started Now I was able to configure the controls within dolphin. I also made a combined hotkey to exit dolphin (In my case the Start and SELECT Button). Switched off Confirm On Stop and Render To Main Window on within the dolphin-emulator Switched off Settings/Streaming/Advanced Options/Start Streaming desktop Restarted steam-link and it worked

I also installed steam-devices on the Raspberry Pi too, but I don't know if it makes any differences. If I want to play a game with a keyboard, I have to plug off the controller before starting steam-link.

@HorseWithForce said in RetroPie Screen Mirroring / Streaming / Casting:

Also the Retro Pi emulation wont start cause it tells me no display connected...

That's probably the reason why it's not working - there's no video device initialized. You didn't mention which Pi model are you using, but as a general solution, configure a video mode in /boot/config.txt and set hdmi_force_hotplug=1 as-well so that display detection is skipped.

As for using the solution on the RaspiOS Bullseye, it will not work due to the fact that the MMAL/DispmanX API is no longer supported with the new KMS ARM driver.

Just out of curiosity, why are you trying to use this solution, if you don't have a display attached to the Pi ? Wouldn't it be easier to install the emulators on your PC/Phone to play ?

I'm running into a similar issue as well. Through searching through the moonlight github it seems the move to SDL2 has caused some issues with RetroPie. The developer of Moonlight has stated that they wont bother with fixing the problem as it comes from the way RetroPie handles controllers using SDL2 framework. Something around how the buttons are mapped and what the system sees. I'd love more help trying to track this down as well.

@Rascas
thanks to you.
