Native ARM build from leaked source

Compiled the Source Engine Leak, modified instructions from James Hughes. These can be used to build native ARM macOS ports of Half-Life, Half-Life 2, Half-Life 2: Episode 1 & 2, Portal, Counter-Strike: Source etc. as long as the necessary game files from Steam have been copied.

xcode-select --install

3. Install required packages from Homebrew (added the jpeg-turbo dependency from instructions)

brew doctor
brew cleanup
brew install sdl2 freetype2 fontconfig pkg-config opus libpng libedit python3 jpeg-turbo

4. Clone the Source Engine GitHub repository

git clone --recursive https://github.com/nillerusr/source-engine
