ACNB Stage 0 - proof of concept build (Windows x64)

A PC source port of Armored Core: Nine Breaker (USA, SLUS-21200) Versus mode, built from decompiled game logic.
No game data is included: you need your own disc image.

1. Put your disc image in the `game` folder (see game\README.md). Any .iso name works; its SHA-1 is checked.
2. Run sourceport\build\acnb.exe.

Keep the folder layout as it is: acnb.exe finds the `game` folder three levels up (sourceport\build -> root).
Fixed settings in this build: interlace off, blur off, all parts unlocked. The Training page is inactive.
Window / audio options: --set video.scale=N, --set video.window=WxH, --set audio.volume=0..200, --mute.
