The Raspberry Pi supports the ability to emulate game systems allowing you to play retro games. Developers are still creating game files for Open Source games that play under these emulators and may be found via searches on the Internet. This section only describes some aspects of how the Raspberry Pi may be configured to play these open source games.
First you will need to retrieve the source for the game emulator and try running it.
sudo apt-get install -y git dialog
git clone --depth=0 git://github.com/petrockblog/RetroPie-Setup.git
Next you can optionally install the blue tooth software
sudo apt-get install bluetooth
sudo apt-get install python-cwiid
sudo python wiimotetest.py
sudo apt-get install wminput
To get a bluetooth remote such as the Wiimote working correctly with the emulator, you may need to additionally configure the mapping of the buttons. Type sudo nano /home/pi/RetroPie/configs/nes/retroarch.cfg and try adding something similar to input_player1_select = c
Additionally, I found the following commands helpful in configure the proper mappings. cat /etc/udev/rules.d/ cd /etc/udev/ cat udev.conf sudo wminput -c buttons -d cat /sys/devices/system/cpu/cpufreq/ nano buttons sudo wminput -c gamepad sudo wminput -d & xmodmap cd /usr/lib/cwiid/plugins ./retroarch-joyconfig
