Kotaku reports that browser-based versions of games including Halo: Combat Evolved, Grand Theft Auto: Vice City and The Simpsons: Hit & Run run well in testing. The report attributes the ports to AI-assisted decompilation, but details about who made them, how they were built and whether they have been challenged by rights holders remain unclear.
Browser versions of Halo: Combat Evolved, Grand Theft Auto: Vice City and other older games appear to run smoothly, according to a Kotaku report based on hands-on testing. The development points to how AI-assisted decompilation may make it faster to recreate games for browsers, while leaving open questions about the ports’ creators, methods and copyright status.
Kotaku said it tried browser ports of several games linked in a social media post, including Call of Duty: Black Ops, Halo: Combat Evolved, Skate 3 and The Simpsons: Hit & Run. The report described some of the versions as running very well; it did not provide independent performance measurements or a systematic comparison with the original releases.
The author said one of four Halo: Combat Evolved browser versions tested had working online servers and a low ping. The report also said the tested Simpsons port appeared to run at up to 240 frames per second. Those are observations from the author’s testing, not verified performance claims for every version or every user.
The report links the spread of these projects to advances in AI-assisted decompilation, naming Claude Opus 5.5 as the model it says is behind a recent wave of projects. It says the tools can help reconstruct game code more quickly than traditional manual work. The article does not independently establish how each browser port was made or confirm that the named model was used for every example.
Browser Ports Test Copyright Enforcement
The reported performance matters because it suggests that some older console games can be made playable in a browser without requiring users to install the original game, at least in the versions Kotaku tested. That could lower the technical barrier to sharing and accessing unofficial ports, and complicate efforts by rights holders to limit their distribution.
However, the report’s observations do not establish that the ports are legal, authorized, safe to use or available consistently. It also does not show that the projects replace commercial releases. The immediate significance is the apparent combination of accessible browser delivery and faster AI-assisted reconstruction, not proof that publishers have lost control of their catalogues.

Older Games Meet Faster Decompilation
Kotaku places the browser ports within a wider wave of AI-assisted game projects that it says appeared over the preceding couple of weeks. It also mentions native-style ports of Fallout and Call of Duty: Modern Warfare, as well as a Super Mario 64 mash-up mod. These examples are part of the report’s account; the article does not provide a complete inventory or independently document how each was produced.
The games discussed largely come from the PlayStation 2 and PlayStation 3 eras. Kotaku argues that modern computers and browsers have sufficient memory to handle games from those generations, and that the newer development is the speed at which AI tools may assist with decompilation. The report contrasts that process with the months of painstaking work it says manual reconstruction could take, but gives no measured time comparison for the specific ports.

Creators, Rights and Access Remain Unclear
The report does not identify the people or groups responsible for each port, explain the exact technical process used, or establish whether the projects include original game assets, require files from users, or rely on other materials. It also does not provide a complete list of working links or confirm how long the browser versions remain accessible.
There is no reported response from Microsoft, Take-Two Interactive or the other companies that own relevant game rights, and the article does not confirm that any specific port has received a takedown notice. Kotaku predicts legal action may follow, but that is speculation in the report rather than a confirmed enforcement step. The legality of individual projects may depend on details not included in the available account.

Publisher Responses and Port Availability
The next developments to watch are whether rights holders comment or take action, and whether the reported browser versions remain online or are replaced by new links. Kotaku expects publishers’ legal teams to face ongoing work, but it gives no timeline for notices, lawsuits or other responses.
Further reporting would also need to establish how the ports were created, what users need to run them, and whether performance can be independently reproduced. Until those details are available, claims about ease of creation, reliability and the scale of the trend should be treated as provisional.

Key Questions
Which games did Kotaku report testing in a browser?
The report names Halo: Combat Evolved, Grand Theft Auto: Vice City, The Simpsons: Hit & Run, Skate 3 and Call of Duty: Black Ops, among others. It does not provide a complete verified catalogue.
Did every browser port work perfectly?
No. Kotaku said several versions ran well, but its account is based on the author’s testing and does not establish consistent performance across all ports, devices or users.
Were the browser ports officially authorized?
The report does not establish that any of the ports were authorized. It also does not confirm whether rights holders have issued takedown notices or made public statements about them.
What role did AI reportedly play?
Kotaku attributes the projects to AI-assisted decompilation and names Claude Opus 5.5 in describing the trend. The report does not verify the tools or workflow used to create each individual port.
