Supermodel emulates Sega's Model 3 arcade platform, allowing you to relive state-of-the-art 3D arcade gaming as it existed from 1996 through 1999. It uses OpenGL, SDL2, and can run on Windows, Linux, and macOS. It also supports network play on low-latency network connections.
Ensure Apple's Xcode Command Line Tools are installed:
From a terminal:
xcode-select --install
Ensure SDL2 is installed. Download the latest *.dmg files from both of the links below, and install per the READMEs in the .dmgs (i.e. in "/Library/Frameworks")
And then build Supermodel:
make -f Makefiles/Makefile.OSX
For network support:
make -f Makefiles/Makefile.OSX NET_BOARD=1
If you try and run a macOS binary that was downloaded from the internet and/or built on a different machine, you need to grant macOS permission to execute the binary (just 1-time):
Open the folder containing the binary in Finder, and right (or ctrl) click on it:
Click "Open" when the following dialogue box appears : "macOS cannot verify the developer of “supermodel-git-xxxx”. Are you sure you want to open it?"
Close the terminal window that opens (after clicking open)
