I've just installed LibreElecc 9.2.1 on a brand new pi4B 4BG, globally works like a charms for music and video, but I'm unable to have any game working. For example, I've used Internat Archive Game Launcher to download some amiga games, launched the game, installed emulator and dependencies from standard LibreElect repo - namely Commodore - Amiga (P-UAE) - and get below error.

Did I missed an obvious first step ? First time I try retro gaming so maybe this is a newbie question, any tip would be appreciated.
