Silent Hill PC Port — macOS arm64 (Apple Silicon)

Requires the original disc image in gamedata/ (not included).

Runtime dependencies (Homebrew):
  brew install sdl2 openal-soft
(libjpeg is bundled; no jpeg-turbo install needed.)

The build is unsigned. Before the first run, clear the quarantine flag
on the WHOLE folder so the binary AND the map .dylibs load without
per-file Gatekeeper prompts:
  xattr -dr com.apple.quarantine .
Then:  ./SilentHillPC
