Raspberry Pi for Gaming – The Light Weight Retro Console

For those of you looking for a cheap dedicated arcade/console PC consider the Raspberry Pi for gaming.  It is a credit card sized integrated PC board that has USB port, LAN connection, and SD card port.  You can get an entire setup for around $80 that includes all the accessories plus a couple gamepads.  It will handle many emulators and has a considerably good looking frontend interface for arcade games.  I would go bigger if you are doing a full size arcade machine as I discuss in my “How to Build an Arcade blog“. If you want essentially a small footprint console machine that can play a majority of the late 80s, early 90s console games on some gamepads than this may be your ticket.

We also just released our first CNC Bartop Arcade Kit if you need a cabinet.  It goes together via camlock system with just a philips screwdriver.  You can even get custom graphics!

Where can I get it?

Like anything, I have found Amazon has the best price and shipping with accessory kit.

This kit will get you everything you need to get started on this awesome project.  The B+ version simply has 4 USB ports and uses a micro sd card instead of the older B version that had 2 USB ports and utilized a full size SD card.

The newly released pi 2 has a quad core with 1gb memory.  I would suggest this model.

The SD card size needed depends on how many emulators you plan to run.  The operating system takes up 4 gb.  Nes, SNES, and Sega Genesis will take up another 4gb.  If you plan to run more than that I would consider a larger card based on your needs.

Some options for a Console Type Gaming

These are a great option if you want to have a similar feel to the actual console.

Setup

I set this up a couple years ago and it was a real pain in the ass.  They have greatly automated and improved it, but there are still a few steps.  This process will be the quickest way to get it going.  I still have found most other blogs and posts are severely out of date with the older manual way to set this up.  Hopefully this helps you get playing quick.

RetroPie Image File

RetroPie is essentially an image file you can put on your sd card that comes ready to go.  It has all the emulators listed above pre-installed along with the frontend Emulation Station.  It will save you a ton of time.  So grab that image here.

I found the Google drive mirror in that link downloads the fasts.  The file is 1.2gb compressed and like 3.4gb uncompressed.

retro pie image download

 

Go ahead and extract the image file so you have the iso file ready.

extract

Here is what the iso file will look like

iso file

Now we need to image the sd card using a free program called Win32 Disk Imager.  Install the program, insert you SD card into your PC, and then open the program.

You will need to push the folder icon and select the iso image you extracted.  Then select the drive letter of your SD card.

image

Press Write and it will take a few minutes for the program to image the device.  Once it is done remove the SD card from the computer.

Raspberry Pi Setup

Don’t get overwhelmed here if you are not familiar with Linux or command line.  There is very little and this guide will walk you through step by step.

Insert the SD card into the raspberry pi along with your keyboard (wired or wireless is fine as long as it is USB).  You need network for this so please connect the Ethernet as well.  Power it up.

The initial boot will go ahead and boot Emulation Station all the way.  This is fine, but we have some things to do first before we start playing.  Once it is fully booted press “F4” on your keyboard to exit out of Emulation Station and to the command line.

retropie cmdline

Let’s go ahead and update the raspberry pi firmware if it is available.

Type “sudo rpi-update” without the quotes and press enter

20150101_221743_resized

It will update or tell you if you are on the newest version

raspberry pi update

Now let’s go into the retropie configuration by typing in “sudo raspi-config” without the quotes and press enter

20150101_221854

Here is what the configuration screen looks like.  Hit enter on option 1 to Expand the File System.  This will ensure you get all the space available on your SD card.  This is a very important step.

20150101_221902

It will show success

20150101_221914_resized

Next go to option 7 for overclock so we can speed up the pie

20150101_221938_resized

I set it to high and press enter.

20150101_221949_resized

It will show you success.

20150101_221956_resized

Next go to option 8 for advanced options then to option A4 for SSH

20150101_222008_resized 20150101_222030_resized

Enable SSH as that will allow us to copy games to our system later

20150101_222039_resized

Success

20150101_222047_resized

On the Audio Settings highlight HDMI and press enter

20150102_023311_resized

Memory Split change the number to 384

20150102_022703_resized

We are done with the CMD line and configuration for now.  Hit finish and reboot.

20150101_222126_resized

Copying Games to Emulation Station

The system is playable, but too bad you don’t have anything play yet.  Let’s get your games “rom files” transferred over to your raspberry pi.  We will use WinSCP to transfer the game files.  You can use CyberDuck for Mac.

Just do the basic installation.  I would do the Commander view when it asks you for that in the installation.

WinSCP

 

Go ahead and launch upon installation finish or after it installs.

  • Enter the ip address of your raspberry pi (press “F4” on the raspberry pi and the cmdline welcome screen will give the ip address to you)
  • Username is “pi” without quotes
  • Password is “raspberry” without quotes
  • SFTP for connection type is fine
  • Click log in and yes to any prompts

WinSCP connect

Now you are ready to transfer or upload game files to the raspberry pi.  On the right is your raspberry pi setup.  Navigate by clicking on the folders RetroPie -> roms.  You will see the available systems.

WinSCP retropie

Choose the folder of the system you want to transfer the games to.

NOTE: THE SYSTEM WILL NOT SHOW UP IN EMULATION STATION UNLESS THERE IS AT LEAST 1 ROM IN THE SYSTEM’S ROM FOLDER

For this example we will do nes games, but the process is the same.

Find you local folder that contains the nes “game” rom files.  NOTE: THE ROM FILES CANNOT BE ZIPPED.  Other frontends are fine with zip files, but they will not be recognized in emulation station.  If you want to unzip all in 1 action.  Ctrl A to select all of them and right click.  With Winrar installed you can press “Extract Files”.  All will extract in one folder.

extract all roms

Here is the output of .nes rom files.

roms nes extension

Select that folder on the left side of WinSCP and press upload making sure you are in the nes folder (in this example) to transfer the games.

WinSCP retropie rom transfer

You will repeat this process for all the system you want to add to emulation station.

Controller Setup

Here is a video on how to setup a wired Xbox 360 Controller and it works for the afterglow as well.  If you want to setup a XinMo USB encoder for actual arcade controls like in our control panel bundles, please read the steps below as it is a little bit different process.

 

Go ahead and plug in the USBs on your controllers and boot the raspberry pi.  When it boots it will recognize your gamepads and help you automatically configure them for the frontend.  Simply follow the prompts of holding down a button on player 1.  Then press on the gamepad what the prompts as you (up, down, left, right, a, b, select, start, etc).  Do the same thing for player two.  You can also reconfigure gamepads at any time by going into the main menu and controller input.


20150102_002340_resized 20150102_002355_resized

Unfortunately above only configures the frontend controls, not the emulators.  What this means is you can navigate the menus, but will not be able to play any games yet.  We have some work to do to get the controls setup.

Note: For the XinMo USB encoders only.  You need to do a custom kernel update to correct an autofire setting and so both players show up.  Download the 100mb Kernel file here.  Using WinSCP as you did above for adding games you need to copy the kernel file to your raspberry pi.  

Once it is copied over, let’s install it by F4 to terminal on your pi and entering the following commands.

  • cd into the folder your copied the kernel into then,
  • tar -xf custom_kernel_1.20150317-1.tar.gz
  • cd custom_kernel_1.20150317-1
  • sudo ./install.sh

You can test that everything is working by entering the following commands

  • sudo apt-get install joystick
  • jstest /dev/input/js0

This will let you press buttons and joysticks and make sure they are what you expect.

Once it installs you are all set to continue below.  If you have any issues FeederChain is the man that so graciously created this kernel and you can see the most up to date forum post here.

First thing we have to do is setup the 1 player controller on the raspberry pi.  On the raspberry pie press “F4” key to get back to the command prompt.  The text below is a sample of the snes USB controller.  Watch the video for the xbox 360 controller setup.

SNES USB

Type in the following 2 lines one by one pressing enter after each one.

cd /opt/retropie/emulators/RetroArch/installdir/bin
sudo ./retroarch-joyconfig -j 0 >> /opt/retropie/configs/all/retroarch.cfg

FYI the -j 0 is a zero not the letter o

20150102_020219_resizedCapitalization and spacing does count.
20150102_020255_resized
It will prompt you to press enter on the keyboard and configure your controller.  Like we did in emulation station press enter and then the corresponding controls on your gamepad as it prompts you.

20150102_014750_resized

Congrats.  You can now play games in the emulators.  Our victory is sweet, but short.  There are a few more steps to finish off the controls.

We need to go back to our pc and again open WINSCP.  Connect to the raspberry pi as before.  Once connected you will need to change to the “root” directory in at the top.  Then follow the folders to /opt/retropie/configs/all/

retroarch config

In that folder you will see a file called retroarch.cfg.  Download that to your PC as we have to make some modifications and additions.

The easiest way to modify this file is with a program called Notepad++.  Do not use normal notepad as it will be too jumbled (yes, even with word wrap turned on).  Once you have installed NotePad++ launch it and open the retroarch.cfg file you downloaded to your machine.

retroarch config notepad++

Once in there at the bottom you will find a long section with a bunch of entries that begin with “input_player1_”.  Copy that entire section and paste a copy below that section.

retroarch config notepad++ p1 highligh

We are going to modify the newly copied section ONLY by changing the “input_player1” to “input_player2_”  The easiest way to do this is to press ctrl f to bring up the find window.  Click the replace tab and put the “input_player1” in the find and “input_player2_” in the replace.  DO NOT REPLACE ALL.  Hit find next and stop when you get to the first entry of the copied section you did.  Start replacing them one by one until you are at the bottom of the file.

retroarch config notepad++ p1 replace

Go to the top of the section you just did and change the “input_player_joypad_index” to 1 (this should allow us for 2 players)

retroarch config notepad++ p1 joystick index

Almost there!

We want to add a few lines to make life better when playing games.  Add the following to the end of the file.

input_enable_hotkey_btn = “8”
input_exit_emulator_btn = “9”
input_save_state_btn = “5”
input_load_state_btn = “4”
input_volume_up_axis = “-1”
input_volume_down_axis = “+1”

And save the file.

retroarch config notepad++ extra functionality

What those last lines will do

  • Allow you to exit the game by holding down select button then pressing start
  • Allow you to save the game by holding down select button then pressing right paddle
  • Allow you to load the game by holding down select button then pressing left paddle
  • Allow you to turn up the volume by holding down select button then pressing up on the directional pad
  • Allow you to turn down the volume by holding down select button then pressing down on the directional pad

The last thing is to upload the modified retroarch.cfg file back to the raspberry pi.  You should still have the windows open in WinSCP where you can press upload and overwrite the file on the raspberry pi.

retroarch config notepad++ upload

After it is done, reboot the Pi and test your controls in the game including the new functionality in the bullet list above.  Congrats that was the most difficult part of this whole process.

Game Information and Artwork

You should see all the systems in which you added rom files to the correct folder on your raspberry pi.  You can see I have the Nintendo Entertainment System (nes) available in my example.

Emulation Station Nes

Let’s “scrape” the system game files so they get game information along with the box artwork.  Keep in mind you still need to be connected to the internet on the raspberry pi for this to be able to work.  Press the Start button on your controller to access the main menu.

20150102_002423_resized

Press “a” on your controller for the Scraper

20150102_002440_resized

TheGamesDB is good for the Scrape from setting.  Go to Scrape now and press “a” on your controller

20150102_002450_resized

 

This is where you can tell Emulation Station what systems you want to scrape.  I would leave the filter on “Only missing image” and select the systems option.

20150102_002459_resized

You can un-check any systems you do not want to pull game information and artwork for then go back.

20150102_002510_resized

Before you start the scrape I would turn the “user decides on conflicts” off.  If not then it will prompt you to babysit the entire process and verify all the information.  If your games are named properly via how you got them then they should be good.  Turn it off and hit start.  It will begin to pull game information.

20150102_002559_resized

 

Sorry!!!  This will take a while, like hours.  I would just let it run and go do something else knowing you are very close to having something you never dreamed possible when you were a kid.  Access to everything console all at once.

Conclusion

Well you did it!  Now you have access to all the console game of your childhood (or your dad’s at least) at the press of a well organized button.  Yes, this will make your friends jealous.  Send them our way.
