@azsorlex26 Each package exposes a standard set of commands to be executed - sources, build, install, remove, configure. Most packages have these options, there might be packages with special functions.
Look at https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/packages.sh#L55 and https://github.com/RetroPie/RetroPie-Setup/blob/bfaedb92cb86335b7fec34d23fb39890455ae05f/scriptmodules/packages.sh#L162 to see how the retropie_packages.sh script works.
