yo @isofrieze.com just wanted to say thanks for @rgmechex.com your videos are extremely cool and informative. After watching for a few years I finally motivated myself to dive into the @gbdev.io tutorials and docs and pick up some assembly knowledge in Oct 2025.
Now I'm making a GBC homebrew game :)
