Well you need several packages & PulseAudio to use video previews in ES. I guess that's the reason why Gamestarter doesn't support this because this needs deeper changes in your system. As stated in my start post maybe one day Retroplayer will be feature complete but right now it's just a proof of concept & work in progress to me.
What did you do? Install Docker & place the bios files and iso in the directories and run the game afterwards? ES has nothing to do with this since it just runs the PCSX2.start command and points to the game you want to run. Or do you try to load real game discs?
Well looks like the LE 9.1 addon repo isn't populated right now so I have to probably revert this distro: bump OS_VERSION/ADDON_VERSION to 9.1 · LibreELEC/LibreELEC.tv@8964c21 · GitHub and rebuild the images.
Thank you for the explanation. I think I'll update the official libreelec installation with yours. I have a question about this: if I upgrade the existing installation with yours, have I to uninstall some addons first (ex. retroarch, emulationstation, amazon vod, tvheadend server, netflix) or it'll update those addons with yours?
Thank you
