In following section we will explain the steps to install gaming emulator to make Pi as gaming console.
For making Pi as gaming console we need to install Retro Pi.
We will download retro pi using git command
git clone --depth=0 https://github.com/petrockblog/RetroPie-Setup
Do remember to run commands using Pi user not the root.
It will download the packages in the directory named Retropi-Setup
then we need to install the downloaded packages, go to directory Retropi-Setup and give following commands
chmod +x retropie_setup.sh
It will start installation
Once installation is finish reboot the pi you will see retro pi screen during reboot.
After installation you can start emulator.
once you start the emulator using command “emulationstation” It will try to configure controller. If you have usb controller you can attach with Pi and then start emulator, for the first time it will ask to configure it and close emulator again as there will not be any game.
After installation we can see many folders created for in /home/pi/RetroPie/roms/<ROM>
first you can download the rom for games and put in rom directory example I have put sega32x.zip and extracted under sega32x
We will start emulator and you will see games under roam names.
you will see many games under Sega
When i configured my controller first time i configured wrong button and I was searching the way to reconfigured but there is not option.
Finally the solution is there is hidden folder under pi user (.emulationstation) you delete that folder and once you start the emulator again it will ask to configured controller device ………
