Sorry, i've just noticed entering in each package menu that a few ones can just be downloaded from source and compiled.

Thanks.

@StigNasty said in Another total noob question:

Two questions: 1. What does this mean? 2. How do I do this?

It means you've been using a development branch of the RetroPie-Setup script and that branch (version) will be deleted, so you'll not be able to update in the future.

From the command line, execute the following:

cd $HOME/RetroPie-Setup git reset --hard git checkout master

OR

cd $HOME sudo rm -fr ./RetroPie-Setup git clone https://github.com/retropie/RetroPie-Setup
