Kotaku reports that browser-based ports of games including Halo: Combat Evolved, Grand Theft Auto: Vice City and The Simpsons: Hit & Run ran well in its testing. The report attributes the recent wave of ports to AI-assisted decompilation, but details about the tools, creators and legal status of individual projects remain unclear.
Browser ports of Halo: Combat Evolved, Grand Theft Auto: Vice City and The Simpsons: Hit & Run have appeared online, and Kotaku says several ran well during its tests. The report links the projects to AI-assisted game decompilation, a development that could make it faster to recreate older games, while leaving questions about copyright enforcement and the scope of the tools’ capabilities.
Kotaku reported that it tested browser versions of several older games, including Halo: Combat Evolved, Call of Duty: Black Ops, Skate 3, Modern Warfare 2, Vice City and The Simpsons: Hit & Run. The article described some of the ports as running very well, but did not provide independent technical benchmarks or a full accounting of which versions were tested.
The report says one of four Halo: Combat Evolved browser versions it tried had working online servers and what the writer described as low ping. Kotaku also said The Simpsons: Hit & Run appeared capable of running at 240 frames per second. These are the outlet’s observations, not a verified performance assessment across devices or browser configurations.
Kotaku attributed the broader wave of projects to recent advances in AI-assisted decompilation, naming Claude Opus 5.5. It said hundreds of emulators and game projects had appeared over the prior couple of weeks. The source does not detail the methods used to produce each port, establish that every project relied on the same AI model, or independently verify the scale of the reported activity.
Why Easy Browser Ports Matter
If the report’s account is representative, browser-based ports could make older games easier to access: players may not need to install the original title to try a version running in a browser. The same convenience could make unauthorized copies more visible and easier to share, potentially raising enforcement concerns for publishers and rights holders.
Kotaku argues that removing individual ports may not stop new ones from appearing if the work can be repeated quickly. That is a concern raised by the report, not evidence that takedowns will fail or that every project can be recreated with little effort. The practical effects depend on how the ports were made, what files they distribute, and whether rights holders pursue them.
The story also draws attention to a shift in the perceived barrier to game preservation and reverse engineering. A process that once demanded substantial specialist labor may become more accessible with capable AI tools. But this report does not establish how much human expertise remains necessary, whether the resulting software is legally distributable, or how reliably the approach works across games.

A New Wave of Game Reconstructions
Kotaku places the browser ports within a wider cluster of recent projects it describes as AI-decompiled games and emulators, including native ports and mash-up modifications. Its account says these projects began appearing in the weeks before the article, though it does not provide a project-by-project timeline or a dataset documenting the trend.
The report contrasts older, manual decompilation work—which it says could take months—with a workflow in which an AI tool is left working for an extended period. It also notes that many of the games involved date from the PlayStation 2 and PlayStation 3 era. The article’s comparison between console memory and a browser’s memory use is meant to explain why modern browsers can handle demanding software; it does not, by itself, demonstrate how any particular port was engineered.
On October 8, 2026, an account identified in the source as Radiant Optimizer posted that games including Black Ops, Skate 3, Halo and Modern Warfare 2 could be played in browser tabs. That social-media post promoted the ports, while Kotaku’s later hands-on account supplied the reported performance observations.
“Some of them seemed to be borderline flawless.”

How The Ports Were Built
The available account leaves key technical and legal details unresolved. It does not identify the people behind each port, provide source code or explain whether the projects contain original game assets, require game files supplied by users, or distribute copyrighted material themselves. Those distinctions can matter when assessing what a project does and how rights holders might respond.
It is also unclear how many ports remain accessible, whether their performance is consistent across devices, or whether the online Halo servers will continue operating. Kotaku’s report does not include statements from Microsoft, Take-Two Interactive or other publishers about specific projects, and it does not confirm that Claude Opus 5.5 alone produced the ports.

Publisher Responses And Port Availability
The next developments to watch are whether the browser ports remain online and whether affected publishers or rights holders issue takedown requests or public statements. Kotaku anticipated possible legal notices, but the source material does not confirm that any had been sent at the time of publication.
Further reporting would need to establish how the projects were produced, what material they make available, and whether their creators can reproduce them after removals. Until then, the confirmed picture is limited: the ports were reported online, and Kotaku said several worked well in its own tests. Their availability, technical reliability and legal consequences remain unsettled.

Key Questions
Which games did the report say were available as browser ports?
Kotaku listed Halo: Combat Evolved, Grand Theft Auto: Vice City, The Simpsons: Hit & Run, Call of Duty: Black Ops, Skate 3 and Modern Warfare 2 among the games featured in browser-port posts or its testing.
Did Kotaku verify that the ports ran well?
Kotaku said it personally tested several versions and described some as running very well. The article did not publish formal benchmarks, and the findings should be understood as the outlet’s reported observations, not a guarantee of performance on other systems.
Were the games created entirely by AI?
The report attributes the wave of projects to AI-assisted decompilation and names Claude Opus 5.5. It does not explain the human work involved in each port or establish that every project was made with that model.
Have publishers taken legal action?
The supplied report speculates that publishers could send cease-and-desist notices, but it does not confirm that any legal notices were issued against the specific ports discussed.
