This is the reconstructed C and C++ source of Wing Commander II as shipped in Wing Commander: The Kilrathi Saga (1996), with the SDL2 port's code stripped out. Built with Microsoft Visual C++ 4.1, it reproduces the original Win32 WC2.EXE byte for byte: all 714,752 bytes, including code, data, padding and PE/debug metadata.

Every reference build checks the complete executable against the retail SHA-256 and fails on a mismatch: f5e133e8eca8eb1a02e21a7d1afbb44d082e384a38d39db58a694371fa583bbe.
