For my games that are hosted on here the platforms you can play on RetroPie, to do that you will need a Godot scraper. A RetroPie itch.io Godot Scraper is a tool for RetroPie to scrape Godot games hosted on here

On RetroPie press F4, that will bring up the command prompt then type this line and press enter:

cd /home/pi/

then type this line and press enter:

git clone https://github.com/hiulit/RetroPie-Itchio-Godot-Scraper.git">https://github.com/hiulit/RetroPie-Itchio-Godot-Scraper.git</a>"><a href="https://github.com/hiulit/RetroPie-Itchio-Godot-Scraper.git</a>">https://github.com/hiulit/RetroPie-Itchio-Godot-Scraper.git

last type this line and press enter:

cd RetroPie-Itchio-Godot-Scraper/

after everything is downloaded restart RetroPie then go to file manager and search for
