FourthTube is a homebrew application for the Nintendo 3DS that allows you to watch YouTube videos. It is a fork of ThirdTube, a now broken app that did the same thing.

As this app is still in the beta stage, you may and will encounter crashes and other bugs. If you find one of those, it would be helpful to open an issue on the GitHub repository. |
