Install RetroPie on RasberryPI 2
The PC in my arcade machine has died so rather than put another full size PC I thought the Rasberry PI 2 looked perfect for the job. The next few guides will explain how to install and set this up. This was all done on MacOSX, so the guide will not exactly be correct if not completed on this OS.
Get the latest version of the RetroPie software for RPI 2, at the time of this guide the current version was V3.0, use this link RetroPie Download.
Locate the downloaded file and uncompress, the file you will be left with is a “.img” file.
Mine was called “retropie-v3.0-rpi2.img”
Put the SDCARD your reader so it can be seen by the MAC.
Run this command to locate the SDCARD
From this list of drives, I determined my disk was “/dev/disk3″, we now need to unmount this drive.
NOTE: Ensure you have a backup of everything on the SDcard as it will all be deleted
Run this command to unmount the drive
diskutil unmountDisk /dev/diskN
–N being the number of deivce, in my case a “3”
Now we will re-image the sdcard, using “dd”, ensure you are in the correct locations (path) when running the below command
sudo dd if=retropie-v3.0-rpi2.img of=/dev/rdisk3 bs=1m
Change the .img name to your file name and location, and undate the “rdisk3″ to the disk number that you located earlier.
You will see a screen similar to the below when complete, this could take some time. Just let it run, it will appear as if nothing is happening.
Now remove the sdcard from the pc and insert into your Rasberry PI 2 and boot.
