Halo, Vice City and Hit & Run in a browser tab: the vibe-coded port wave
On 9 October, Kotaku's Lewis Parker tried a batch of browser ports that had spread from a post on X: Halo: Combat Evolved, The Simpsons: Hit & Run, GTA: Vice City, Call of Duty: Black Ops and Skate 3, said to have been decompiled and rebuilt with AI. Most of them ran well. Hit & Run reached 240 frames per second, and one Halo port had working online servers. We looked at the ones we could find to see where the game files come from, because that decides whether a port is a tool or a download.
Why the game files matter
A decompilation is code; the levels, models, music and voices are the publisher's. A port that asks you to supply those files from a copy you own sits in the same place as the PC ports we list. A port that loads the whole game the moment you open the page is handing out the game itself. Our piece on why browser ports vanish explains why those disappear: they are the easiest target for a takedown.
What we found
- GTA: Vice City: listed. reVC Web compiles the reVC decompilation to WebAssembly and streams the game's files from your own installed copy. Its page and source say no game data is distributed. The decompilation it builds on is the one Take-Two had removed from GitHub in 2021, so this port could face the same pressure.
- The Simpsons: Hit & Run: not listed. The version we found starts loading the game straight away, with no step that asks for your files.
- Halo: Combat Evolved: not listed. One browser port is behind a Cloudflare warning that the site has been reported for phishing. Another loads Halo maps immediately, which means it hosts the game data. For a legitimate way to play Combat Evolved on modern devices, see OpenCE.
- Black Ops and Skate 3: Kotaku doesn't say where these are hosted, and we didn't find versions that use your own copy. Skate 3 on PC already has a recompilation that does.
Some of these sites also host ports of games still on sale, from Stardew Valley to Among Us, loaded in full in the browser. That isn't preservation.
Publishers are already responding
A week earlier, Kotaku reported that Activision had a clip of the AI-driven Modern Warfare 2 decompilation removed as a copyright claim, and that the creator of an AI-built Fallout project set in New York abandoned it after an alleged cease-and-desist from Bethesda. Kotaku's view is that takedowns may not keep up, because a new version can be generated overnight. That may be true for the hosting sites. It doesn't change what's safe to use: a port that runs on your copy, from a source that says where the code came from.
The useful part
Strip out the piracy and something real is left. A decompiled game can run in a browser at full speed on hardware that never ran it, with no install, as reVC Web shows with the player's own files. The same work powers native PC and handheld ports, and browser builds of projects we already list, like Golden Balloon for Diddy Kong Racing and PSP Web Recomp, follow the same rule: bring your own game.
