This guide is a manual process to recreate the stock SD image RetroPie released on the RetroPie Website for the Raspberry Pi. If you aren't comfortable with the terminal you would be wise to just use the RetroPie SD image provided.
If you are trying to follow this guide because you want the PIXEL desktop environment, you can already install it on the stock RetroPie SD image by following the guide here
RetroPie can also be installed on most debian based distros, a guide for installing RetroPie on Ubuntu on a PC can be found here
The RetroPie SD image is built on top of Raspbian lite (Raspbian without the PIXEL desktop environment) RetroPie can also be installed on top of the full Raspbian but you can't run Retropie and PIXEL at the same time, you will need to logout of the PIXEL desktop environment in order to run emulationstation and the emulators RetroPie installs.
Raspbian now automatically expands the filesystem so that step is no longer necessary.
You can check your free disk space with
/dev/root is your main partition. Then, I would recommend to update and upgrade the existing APT packages with
sudo apt-get update && sudo apt-get upgrade
Verify Locale Settings
Most of the install scripts will attempt to install a variety of packages and libraries that each emulator requires. These installations will fail if your system locale settings are invalid. You can easily verify this by executing
locale command. A valid locale will return values set for all options, such as in the example below.
LANG=en_US.UTF-8 LANGUAGE=en_US:en LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_PAPER="en_US.UTF-8" LC_NAME="en_US.UTF-8" LC_ADDRESS="en_US.UTF-8" LC_TELEPHONE="en_US.UTF-8" LC_MEASUREMENT="en_US.UTF-8" LC_IDENTIFICATION="en_US.UTF-8" LC_ALL=en_US.UTF-8
If any of the above configuration lines are unset (particularly LANG, LANGUAGE, and LC_ALL), you should set them before installing RetroPie. The easiest way to set each item is to use the
update-locale command, such as
$ sudo update-locale LC_ALL="en_US.UTF-8".
Users can also set the local through the
A reboot is required before these changes will be reflected by the
Verify the allocated video memory (memory split)
Running Emulationstation requires a larger than default GPU memory split. Make sure you reserve enough memory for Emulationstation by modifying the /boot/config.txt configuration file or by using
raspi-config as described in the Memory Split page.
A reboot is required after any modifications to the video memory allocation.
After that, we install the needed packages for the RetroPie setup script:
sudo apt-get install git lsb-release
Then we download the latest RetroPie setup script with
cd git clone --depth=1 https://github.com/RetroPie/RetroPie-Setup.git
The script is executed with
cd RetroPie-Setup chmod +x retropie_setup.sh sudo ./retropie_setup.sh
The screen should look like this then:
Basic Install >> Quick Install
This will install the core and main packages which are equivalent to what is provided with the RetroPie SD image.
Now, you have to copy your rom files into the ROMs directory. If you followed the steps above the main directory for all ROMs is ~/RetroPie/roms (or /home/pi/RetroPie/roms, which is the same here). In this directory there is a subdirectory for every emulated system, e.g., nes, snes, megadrive. Attention has to be taken for the extensions of the ROM files. All the information needed for each system is detailed in this wiki (see wiki home page or sidebar for systems)
EmulationStation can be run from the terminal by typing
emulationstation in the terminal
Say you don't want to bloat your system with all of RetroPie - you also have the option to only install the emulators you want.
When you select Manage Packages, you will first want to start by installing the core packages.
The core components needed for RetroPie to function are: - RetroArch: Frontend for the libretro api, necessary for most emulators to run. - EmulationStation: Frontend for sorting and launching all of your games. - RetroPie Menu: Menu in emulationstation for simpler configuration of your system. - Runcommand: The runcommand launch menu that assists launching your games with proper configurations see related wiki page HERE.
Main / Optional / Experimental
Emulators can be installed and updated individually from the Main, Optional, and Experimental packages.
If you want to use samba shares you can set them up from the setup/tools option of the retropie setup script.
Boot to emulationstation
Follow the steps here: https://github.com/RetroPie/RetroPie-Setup/wiki/FAQ#how-do-i-boot-to-the-desktop-or-kodi
If you're booting to the desktop you'll want to disable the retropie splashscreen from the setup script first.
On Debian Jessie add
consoleblank=0 to the existing line in
/boot/cmdline.txt (with a space before it so it's an additional parameter). This prevents the screenblanker kicking in. With it, runcommand dialog is always displayed.
There is also a gui option in RetroPie-Setup -> Configuration / Tools -> Raspbian Tools to disable the blanker, but it doesn't work in Jessie due to a Debian bug.
