The year is 2006. A developer in Kyoto compiles a build of a platformer. In milliseconds, thousands of lines of readable C logic—painstakingly written to handle the physics of a jumping character—are crushed into raw hexadecimal. The variable gravity_constant becomes 0x4000000 . The function RenderShadow() becomes a memory address offset. The game ships; the source code is archived, perhaps eventually lost to time or a server wipe. Step 3: Automated Analysis Runs at 67 MHz
