Classic Games Like Halo, The Simpsons: Hit And Run, and GTA: Vice City Shine in New Browser Ports

In recent weeks, a surge of AI-decompiled emulators and games has emerged, thanks to the impressive capabilities of Claude Opus 5.5, which excels at decompiling source code.

This means that the source code for games can now be compiled and reconstructed in record time—something that previously took developers months to accomplish. The influx of “native” ports for titles like Fallout and Call of Duty: Modern Warfare, along with AI-generated mash-up mods like Super Mario 64 within Elden Ring, are direct outcomes of this advancement.

However, the most alarming development is the appearance of AI-decompiled web browser ports for games such as Call of Duty: Black Ops, Halo: CE, Grand Theft Auto: Vice City, Skate 3, and The Simpsons: Hit and Run, which actually perform quite well.

While legal teams for companies like Take-Two and Microsoft can issue cease-and-desist orders to remove these ports, the ease and speed of their creation raise concerns about the potential for more to pop up in their place.

PLAY ALL THESE GAMES IN YOUR BROWSER

Your PC does not need the game installed!

You can now enjoy Black Ops zombies, Skate 3, Halo, MW2, and more—all running in a browser tab. Check the comments for the full list.

School gaming is about to get exciting.

This situation resembles a game of IP protection whack-a-mole on a scale reminiscent of the early days of pirated DVDs. It’s hard to see how this can be contained, especially since many of these ports run exceptionally well.

I tested several of the web browser ports mentioned, and some were nearly flawless. For instance, The Simpsons: Hit and Run might even exceed its original performance, as I don’t recall it ever reaching 240fps back in the day. Even more concerning is that one of the four different Halo: CE browser ports I tried had functional online servers with impressively low ping.

As much as I hate to admit it, the reality is clear: most of the games being ported to browsers are from the PS2 or PS3 era. The PS3 had about 512 megabytes of RAM, while my web browser is currently using around 1,200 megabytes.

Web browser ports have long since moved past RAM limitations, and the game-changing factor here is that Claude Opus 5.5 allows for overnight decompilation, eliminating the tedious manual coding process of the past.

The future is uncertain, but one thing is clear: video game publishers’ legal teams will be busy for the foreseeable future.
