Enabling the core updater
To play NES games in RetroArch on your Linux system, you must enable the core updater feature, as it is turned off by default. To enable the core updater, you must access the RetroArch configuration file. Follow the step-by-step instructions below to get it done.
Step 1: RetroArch must be started for the first time to create the initial configuration file. Look through your application menu for “RetroArch” and launch it. Then, close the window.
Step 2: Open up a terminal window by pressing Ctrl + Alt + T or Ctrl + Shift + T on the keyboard. Then, open up the RetroArch configuration file in the Nano text editor.
nano -w ~/.config/retroarch/retroarch.cfg
Or, for Flatpak:
nano -w ~/.var/app/org.libretro.RetroArch/config/retroarch/retroarch.cfg
Step 3: Press the End button on the keyboard to tell Nano to jump to the very bottom of the configuration file. Then, press the Enter key to make a new line.
Step 4: Press Ctrl + W on the keyboard inside of Nano. This action will bring up the search function. Then, type in “menu_show_core_updater” in the search box, and press the Enter. By pressing Enter, Nano will take you to the Core updater line in the text file.
menu_show_core_updater="false" to how the code looks below. If you cannot find
menu_show_core_updater="true" to the bottom of the file.
Step 5: Save the edits to the configuration file in the Nano text editor by pressing Ctrl + O on the keyboard. After that, exit the text editor by pressing Ctrl + X.
With the configuration for RetroArch saved, re-open the program and move on to the next section of the guide.
Downloading the NES core
You must download an NES core to handle NES ROMs. Otherwise, RetroArch may not load NES games correctly. Thankfully, RetroArch is very user-friendly, and cores are easy to download. To get an NES core, open up the RetroArch app and follow the step-by-step instructions below.
Step 1: Find the alien icon in the RetroArch menu. Then, use the Down Arrow key on your keyboard to go to “Online Updater” in the alien icon menu.
Step 2: After you’ve located the “Online Updater” option in the menu, press the Enter key to access the “Core Updater” area in RetroArch.
Step 3: In the “Content Downloader” area, there are many different console choices to choose from. Using the Down Arrow on the keyboard, sort through the list and locate “NES / Famicom (QuickNES)” entry, and press the Enter key on the keyboard to download it.
Don’t want to use “NES / Famicom (QuickNES)” as your default NES core in RetroArch? Select one of the other NES / Famicom core choices available. Each of them works quite well in RetroArch and will emulate your favorite NES roms decently.
With the NES core downloaded, move on to the next section of the guide.
