I have a pi2, just got it going using a method, super easy:
$ git clone https://github.com/ian57/Raspicade-Retrogame-2Player-Pi2.git
$ cd Raspicade-Retrogame-2Player-Pi2
Retrogame requires the uinput kernel module. This is already present on the system but isn’t enabled by default. For testing, you can type:
sudo modprobe uinput
To make this persistent between reboots, append a line to /etc/modules (or edit the file) :
sudo sh -c ‘echo uinput >> /etc/modules’
Now we’re in good shape to test it! Retrogame needs to be run as root (need access to memory), i.e.:
Give it a try. If it seems to be working, press control+C to stop the program and we’ll then set up the system to launch this automatically in the background at startup.
sudo nano /etc/rc.local
Before the final “exit 0” line, insert this line:
If you placed the software in a different location, this line should be changed accordingly. “sudo” isn’t necessary here because the rc.local script is already run as root.
Reboot the system to test the startup function:
