@Rhys said in Using Chromium as an "emulator" for Scratch projects:

Does anyone know if there is a way to temporarily enable and disable the GL drivers from the shell, on the fly, without having to do a reboot?

No, unfortunately this is cannot be done on the fly - it needs a reboot and thus would 'break' RetroPie's front-end (EmulationStation).

@Tackskull I know this is an old topic, but I've just installed a new Retropie setup on new hardware on Ubuntu 22.04 and had this exact problem which I've never had before. It was driving me mad, but your solution instantly fixed the issue.

I got the Scratch 2 Editor to work on RetroPie, but I cannot get it to close. I don't see a quit command in Scratch 2, and I cannot find any information about how to close the Matchbox window manager either. Maybe Scratch 3 will work better when they port it to the Pi. I put it on RetroPie-Extras-unstable because of not being able to exit. https://github.com/moonpi/RetroPie-Extra-unstable

@dankcushions aah thanks so its just waiting for me now haha

I decided to move the Scratch 2 port to the unstable RetroPie-Extras at https://github.com/moonpi/RetroPie-Extra-unstable until there is a solution to the not being able to exit problem.
