A fork of the Sega VMS emulator by Marcus Comstedt.

• A C99 compiler (clang or gcc)
• CMake ≥ 3.16
• X11 — on macOS, install XQuartz:

  brew install --cask xquartz

• SDL (optional, for audio)

cmake -B build
cmake --build build

XQuartz must be running before launching the emulator.

• Install XQuartz (run once):

  brew install --cask xquartz

• Reset shell for DISPLAY launch agent registered by XQuartz.

• Start XQuartz and run the emulator:

  open -a XQuartz
  ./build/vms

  If DISPLAY is still unset in your current session, set it manually:

  open -a XQuartz
  export DISPLAY=:0
  ./build/vms
