Shell script to setup Raspberry Pi (TM) with RetroArch emulator, various cores, and EmulationStation as graphical front end.

First of all, make sure that Git and the dialog package are installed:

sudo apt-get update
sudo apt-get install -y git dialog

Then you can download the latest RetroPie setup script with

cd
git clone git://github.com/petrockblog/RetroPie-Setup.git

The script is executed with

cd RetroPie-Setup
chmod +x retropie_setup.sh
sudo ./retropie_setup.sh

Optional arguments can be passed to the script. If called with

sudo ./retropie_setup.sh

the installation directory is /home/CURRENTUSER/RetroPie for the current user, where CURRENTUSER is the home directory of the current user. If called with

sudo ./retropie_setup.sh USERNAME

the installation directory is /home/USERNAME/RetroPie for user USERNAME. If called with

sudo ./retropie_setup.sh USERNAME ABSPATH

the installation directory is ABSPATH for user USERNAME

RetroPie Setup offers the possibilities to only install RetroArch, the cores, EmulationStation, and SNESDev either with pre-compiles binaries or by downloading and compiling the sources. The first method is much faster, but does not offer the latest versions of the individual programs. So, to make sure that you are running the latest versions take your time and let RetroPie Setup download and compile the programs from their sources.

This script just simplifies the usage of the great works of many other people that enjoy the spirit of retrogaming. Many thanks go to them!
