This guide will enable your Raspberry PI to work with NVIDIA Gamestream to stream Steam games to your Raspberry pi. To use this Guide you must have a Gamestream ready PC with a Gamestream enabled NVIDIA GPU.
With this guid you get limelight integrated to Emulation station for quick access and the games will run 1080p / 30FPS with basically zero input lag (tested with a wired connection and Raspberry pi 2)
This guide is intended for Rasperry Pi 2 with Retropie, but should also work on a Pi B+
I strongly suggest you configure your host PC to use a static IP-address, before you start!
In the shell with the PI-user
install limelight:
pi@retropie ~ $ mkdir limelight
pi@retropie ~ $ cd limelight
pi@retropie ~/limelight $ sudo apt-get update && sudo apt-get install oracle-java8-jdk pi@retropie ~/limelight $ wget https://github.com/irtimmer/limelight-embedded/releases/download/v1.2.1/libopus.so
pi@retropie ~/limelight $ wget https://github.com/irtimmer/limelight-embedded/releases/download/v1.2.1/limelight.jar
Next pair your computer with limelight
Lookup your Nvidia Gamestream PC:s IP address
pi@retropie ~/limelight $ java -jar limelight.jar discover
pi@retropie ~/limelight $ java -jar limelight.jar pair XXX.XXX.XXX.XXX
(for xxx.xxx.xxx.xxx use the ip-address found with discover)
Now input the displayed number on the host PC
Next we configure a key map for the USB-controller used with limelight (if event0 does not give you the proper device you can try next event1-event3)
pi@retropie ~/limelight $ java -jar limelight.jar map -input /dev/input/event0 mapfile.map
Add limelight to the ports section of Emulation station for easy access
pi@retropie ~ $ cd /home/pi/RetroPie/roms/ports/
pi@retropie ~/RetroPie/roms/ports $ nano limelight.sh
in nano add this text:
#!/bin/bash
cd /home/pi/limelight/ && java -jar limelight.jar stream -1080 -30fps XXX.XXX.XXX.XXX -app Steam -mapping mapfile.map
(for xxx.xxx.xxx.xxx use the ip-address from before)
press ctrl+x and press y and enter
pi@retropie ~/RetroPie/roms/ports $ chmod +x limelight.sh
restart the raspberry pi and limelight will be available from the ports section
.
