@mitu Oh that's good to know ! I tried running it on the non-Lite, thinking I wanted to avoid missing libraries and the likes (and that for my box64 testing purposes, it was probably best to have a full GUI available), but it probably created issues instead. I'll definitely do that then, project's back on track :) Main issue I had was when compiling MAME libs, any idea if it's still a massive RAM hog ? (if so I had precompiled them anyway, but the compile is probably quite outdated now)

Also just realized, had I double posted ? My first attempt to submit left the page blank and hanging, and when I clicked back to the forum's main page, I was shown my own post, still ready to submit, so I assumed it was a saved draft, sorry for that if it ended up being a double !

@Lolonois Thanks for the guide link too :) Gonna come in handy !

@xallius 3rd party images aren't supported on the forums, especially ones that come pre-loaded with game ROMS.

I'd suggest going back to the seller for support, or install the official image from the Retropie site and then the community will be able to assist you.
