A model read 72,758 lines of 1993 68000 assembly and rebuilt it byte-identical in about an hour.

The author of a 1993 Amiga game originally written in Baghdad ported it to Godot using Claude Fable 5 over a July weekend. Step one converted 34,000 lines of C++ to Godot in about 3.5 hours, playable at 21 minutes. Step two rebuilt 72,758 lines of assembly across 26 files in about an hour, verified byte-identical against the shipped 1993 binaries using vasm. The model decoded the level format in one pass with no hints and recovered undocumented 6-bit map encodings. It also shipped real bugs the author only found weeks later, including a guard collision check extending through floors and doors that never rendered. Byte-identical on the artifact, wrong on the behavior nobody re-tested. Babylonian Twins
