I found on eBay a broken NES and i bought it to make it as a Home Entertainment System, by using a Raspberry Pi 3.
You can use this guide to make your Entertainment System with a Raspberry Pi, like a multi emulator system and of course as Media Center, to be capable to play videos, music, pictures, and more.
A Raspberry Pi 3
RetroPie Pre-made image
An SD card (i used a Samsung EVO 32GB Class 10 Micro SDHC)
HIFI DAC Audio Sound Card Module Board
100CM High Speed HDMI Male to Female Cable Extender
IR Sensor - 38KHz (for Raspberry Pi)
A powered USB hub
1 USB Wi-Fi dongle
Any NES or Mini NES Case
Download the latest RetroPie image and write it on the SD card. Insert the SD Card into Raspberry Pi and power it on. In a few seconds, you will see the RetroPie screen. Now configure your controller and connect Raspberry Pi with your network.
To install KODI, go to RetroPie's Setup and select "Manage Packages" and then "Manage Optional Packages".
From there, go all the way down and select No 308 "Kodi" and then "Install From Binary". When done, restart EmulationStation.
Now Kodi can be found under "Ports" Menu. You can run Kodi from here.
Make Kodi as its own system instead a port
Run Putty and connect to Raspeberry's Pi IP. Login as username "pi" and password "raspberry" (without the quotes) and then run the commands below (one line at a time). If you want to know what every command does, see here:
sudo cp /etc/emulationstation/es_systems.cfg /home/pi/.emulationstation/es_systems.cfg
sudo nano /home/pi/.emulationstation/es_systems.cfg
Now, add the following codeblock anywhere after
