Go over additional installs not baked into default retropie image.
Exit Emulation Station, and telnet into PI. It's easier that way.
1. sudo ~/RetroPie-Setup/retropie_setup.sh
2. To get a tilde I needed to press shift |\ key.
3. Manage Packages.
Install From source always gets latest code but can take a long time.
Install From Binary is much faster/stable but is not always latest source.
I did update Retropie setup script
Then I did basic install. Since I have learned that I did not need to do that
Basic Install: This is intended as a first install and is not required if using a pre-built image. eg When installing RetroPie on top of an existing OS
I have no idea if I should start over or it could cause any harm.
