This seems like a simple thing but can't find any reference or video to anyone doing it....

Maybe something like https://github.com/hanzelpeter/dispmanx_vnc, to stream the PI's video output and connect a VNC client to control and interact. Most likely latency will be a killer for games if you use the 2.4 Ghz Wifi.

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 ?

@dankcushions i have never used it but i have seen this mentioned: https://www.reddit.com/r/RetroPie/comments/5jztlj/how_to_setup_retropie_with_moonlight_steam/

I think I've tried this and Steam didn't like it when EmulationStation tried to launch another process so I wasn't able to actually launch any emulators.

There might be another way to do it by manually added the Windows version of EmulationStation to Nvidia Experience search list and from your launch script you add something like -app EmulationStation (or whatever the file is actually called in Windows).

After you get moonlight install/setup and you're successfully paired with your Windows PC, you can run moonlight list on the Pi and EmulationStation will be on the list.
