How to install game-porting-toolkit (aka proton for macOS)

Half-Life 2 on the Switch

This is a guide for running Half-Life 2 on your Switch. Please be aware that this isn't a great way of playing Half-Life 2 - do not expect this mod to work perfectly.

Thank you to Bringus Studios for fixing save files not showing up!

NOTE: I am assuming that you have basic knowledge about how modding games on the Switch works. I will not provide support for questions like "how do I install Atmosphère / CFW", "how do I make an emuMMC", "how do I extract games", etc. For help with modding your console, see the NH Switch Guide.

WARNING: While this mod should be fairly safe to use, I do not take any responsibility if your Portal save data is deleted, you get banned from Nintendo Switch Online, or if your Switch explodes.
