# Hundreds of AI-decompiled game ports appear

Full title: Hundreds of AI-decompiled game ports appear; browser versions of Halo, Vice City and Black Ops go viral (8.2M-view post), credited to Claude Opus 5.5

In early October 2026 hundreds of AI-decompiled, "vibe-coded" game ports and emulators appeared online. Kotaku (Oct 9) credited Claude Opus 5.5's skill at decompiling and found that browser ports of Call of Duty: Black Ops, Halo: CE, GTA: Vice City, Skate 3 and The Simpsons: Hit & Run ran well, one Halo port even with working online servers. An X post listing them reached about 8.2M views. Publishers had not publicly responded.

## Key facts
- Viral post: @RadiantOpti (Oct 8, 05:35 UTC), 'PLAY ALL THESE GAMES IN YOUR BROWSER... Black Ops zombies, Skate 3, Halo and MW2 and more': ~8.2M views, ~91k likes, ~7.4k reposts (fxtwitter, Oct 10)
- Kotaku (Lewis Parker, Oct 9): 'hundreds of vibe-coded, AI-decompiled emulators and games have appeared out of thin air' in the past couple of weeks 'because Claude's latest update, Claude Opus 5.5, is extremely good at decompiling'; also cites 'native' Fallout and Call of Duty: Modern Warfare ports and AI-made Super Mario 64-in-Elden Ring mods
- Kotaku found some ports 'borderline flawless' (Hit & Run targeting 240 fps); one of four Halo: CE browser ports tried had working online servers
- Most ports are PS2/PS3-era titles; Kotaku argues takedowns by Take-Two, Microsoft and others become 'IP protection whack-a-mole' because new ports are cheap to regenerate
- Unverified: who made each port and which model was actually used; the Opus 5.5 attribution is Kotaku's and the community's, not a per-project disclosure

## What happened

Decompiling a console game into buildable source used to take volunteer teams months or years. In the weeks after Claude Opus 5.5's
release, users reported that an agent left running overnight can do much of this work. The result was a wave of ports to PC and the
browser, shared in X threads that list playable URLs.

## Why it matters

It is a visible sign that frontier coding agents can now reverse-engineer large binaries, with direct consequences for game
preservation, piracy and copyright enforcement. The same capability matters for security: decompilation is a core step in
vulnerability research.
