Hundreds of Classic Games Decompiled With AI in Browser-Playable Versions

In recent weeks, hundreds of classic video games—including Halo: Combat Evolved, Grand Theft Auto: Vice City, The Simpsons: Hit and Run, and Call of Duty: Black Ops—have been decompiled and ported to web browsers using artificial intelligence, with some versions running at performance levels the original hardware never achieved. The wave of AI-generated game reconstructions, termed "vibe-coded" ports, relies on Claude Opus 5.5's ability to analyze compiled machine code and regenerate functional source code. What previously required months of manual reverse-engineering now takes hours; developers report launching decompilation projects in the evening and discovering completed ports by morning.
