A Kotaku report describes browser-based ports of games including Halo: Combat Evolved, Grand Theft Auto: Vice City and The Simpsons: Hit & Run, saying some played smoothly in its tests. The report attributes the recent wave of ports to AI-assisted decompilation, but the tools, legality, reliability and publishers’ responses have not been independently established in the supplied material.
Browser-based ports of games including Halo: Combat Evolved, Grand Theft Auto: Vice City and The Simpsons: Hit & Run have appeared online, with Kotaku reporting that several ran smoothly in its tests. The report describes the ports as AI-assisted decompilations, a development that could make it faster to reproduce older games while raising questions about copyright enforcement and the continued availability of unauthorized copies.
Kotaku said it tried multiple browser ports linked in an online post and found that some appeared to perform well. The games it named included Call of Duty: Black Ops, Halo: Combat Evolved, GTA: Vice City, Skate 3 and The Simpsons: Hit & Run. Its account is a report of hands-on testing, not a published independent technical benchmark.
The outlet said one of four Halo: Combat Evolved browser versions it tested had working online servers and a low ping during its session. It also reported that The Simpsons: Hit & Run appeared to run at up to 240 frames per second. Those observations apply to the versions and conditions Kotaku tested; the supplied report does not establish that every copy works consistently or offers the same performance.
Kotaku attributed the increase in these projects to the capabilities of Claude Opus 5.5, describing the model as effective at decompiling games. The source material does not include independent verification of that explanation, details about the developers’ methods, or confirmation from the AI company. A post by the account Radiant Optimizer, dated October 8, 2026, promoted browser access to several games, but the supplied material does not verify the post’s broad claims that all listed titles run in a browser.
Browser Ports Test Copyright Enforcement
The report matters because browser delivery can reduce the effort needed for a player to try a game: users may not need a console or a locally installed copy if a port is accessible through a tab. Kotaku’s account suggests that some examples can do more than serve as demonstrations, with playable performance and, in one Halo version, online connectivity reported by the outlet.
For publishers, rapid reproduction could complicate efforts to remove unauthorized versions. A takedown may address a particular site or copy, but the report raises the possibility that similar projects could reappear. That is a concern described by Kotaku, not evidence that publishers have already lost control of their games or that any particular legal response will fail.
For players, a working browser version does not establish permission to use it, safety, authenticity or compatibility. The source material gives no information about whether these ports contain original game assets, require files supplied by users, collect data, or expose users to security risks. Their apparent convenience should not be mistaken for an authorized or supported release.

Why Older Games Can Run in Browsers
Kotaku focused on games from the PlayStation 2 and PlayStation 3 era, arguing that their memory demands are within the capacity of modern computers and browsers. It compared the roughly 512 megabytes of memory it cited for the PS3 with about 1,200 megabytes being used by its browser while the article was being written. Those figures are the outlet’s comparison; they do not, by themselves, show that memory is the only technical requirement for running a game.
The larger change described in the report is the claimed reduction in time needed to reconstruct software. Kotaku contrasted AI-assisted decompilation with a process that could previously take programmers months. It also linked the browser ports to a broader wave of AI-related game projects, including native-style ports and mods. The supplied account does not provide project documentation or independent evidence establishing how each example was made.

Testing, Rights and Methods Remain Unclear
The source material does not identify the people or groups behind the ports, provide links that can be independently assessed, or document how the software was reconstructed. It also offers no response from the relevant game publishers or from Anthropic, the company associated with Claude. Kotaku’s account that the latest Claude model drove the wave should therefore be treated as the outlet’s explanation, not an independently confirmed finding.
The legal status of individual projects may depend on details not supplied here, including how the games’ code and assets were obtained and distributed. No specific cease-and-desist letters or legal proceedings are confirmed in the material. It is also unclear how stable the ports are, whether their online features will remain available, and whether the reported frame rate and connection performance can be replicated beyond Kotaku’s testing.

Watch for Publisher and Platform Responses
The next developments to watch are whether publishers seek to remove particular ports, whether the projects remain accessible or reappear elsewhere, and whether their creators publish technical details. Statements from the publishers and the AI company could clarify what they know about the examples and what actions, if any, they plan to take. Until then, the report establishes that Kotaku found several ports playable in its tests, but not how widespread, durable or legally cleared they are.

Key Questions
Which games did Kotaku say it tested?
Kotaku named browser ports of Call of Duty: Black Ops, Halo: Combat Evolved, GTA: Vice City, Skate 3 and The Simpsons: Hit & Run. The source does not confirm that every version circulating online works.
Did the ports run well?
Kotaku said several performed well in its hands-on tests. It reported that one Halo version had working online servers and that The Simpsons: Hit & Run appeared to reach 240 frames per second. These are the outlet’s observations, not results from a standardized benchmark.
Has AI’s role in making the ports been confirmed?
No independent confirmation is included in the supplied material. Kotaku attributed the projects to AI-assisted decompilation and specifically cited Claude Opus 5.5, but it did not provide technical documentation or a statement from the model’s maker.
Are the browser ports authorized?
The source material does not establish whether any specific port is authorized or explain how its creators obtained or distributed game code and assets. No publisher legal action is confirmed in the supplied report.
What happens next?
Possible developments include publisher responses, takedowns, further testing, and technical or legal explanations from the people behind the projects. The report does not state that any of these actions have already occurred.
