Adding ROMs (Game Files)

It is essential to note that you must legally own the game ROMs you use. Downloading copyrighted ROMs without owning the original game is illegal in most jurisdictions.

  1. Transferring ROMs: RetroPie provides several methods for transferring ROMs:

    • SFTP/SCP: The most common method. You can use an SFTP client like FileZilla or WinSCP to connect to your Raspberry Pi (using its IP address, username pi, and password raspberry). ROM files are typically placed in the /home/pi/RetroPie/roms/<emulator_name>/ directory. For example, NES ROMs go into /home/pi/RetroPie/roms/nes/.
    • USB Stick: Format a USB stick to FAT32, create a folder named retropie on it, and then create a subfolder named roms. Plug the USB stick into your Pi, wait for the green LED to flash (indicating files have been copied), and then retrieve the necessary emulator ROM folders from the USB stick and copy your ROMs into them. Then, plug the USB stick back into your Pi, and the ROMs will be copied to the correct directories.
    • Network Share (Samba): RetroPie automatically sets up a Samba share. You can access it by typing \\RETROPIE (or \\your_pi_ip_address) in your Windows File Explorer or using a similar method on macOS/Linux. Navigate to the roms folder to transfer your game files.

  2. Scraping Game Metadata: After transferring ROMs, it’s highly recommended to scrape for game metadata, which includes box art, descriptions, and video previews.

    • From the RetroPie main menu (accessible by holding Start), go to Scraper.
    • Choose your desired scraper (e.g., ScreenScraper, TheGamesDB).
    • Configure the scraper settings and start the scraping process. This will greatly enhance your gaming experience by providing a visually appealing interface.
