Over the past few weeks, hundreds of AI-coded and AI-decompiled emulators and games have appeared out of nowhere. For what? Because the latest Claude update, Claude Opus 5.5, is extremely efficient in decompilation.
In short, a game’s source code can now be compiled and rebuilt in record time, something that previously took coders months. All these “natives” To fall And Call of Duty: Modern Warfare ports and those generated by AI Super Mario 64 inside Ancient Ring mix mods you may have seen this as a direct result.
However, I think today’s example is by far the most concerning development so far, as I am forced to admit that these Web browser ports decompiled by AI call of Duty Black Ops, Halo: CE, Grand Theft Auto: Vice City, Skate 3And The Simpsons: Hit and Run in fact, they seem to work very well.
Of course, lawyers for Take-Two, Microsoft, and anyone else can send cease and desist letters and have them removed. But then what? These browser ports were clearly quick and easy to create, so what’s going to stop people from just coding another version of these browser ports?
PLAY ALL THESE GAMES IN YOUR BROWSER
Your PC does not need the game installed!
you can now play Black Ops Zombies, Skate 3, Halo and MW2 and other GAMES all running in one browser tab. full list in comments.

This is IP protection on a scale not seen since the advent of pirated DVDs. I really don’t know how you put the genie back in the bottle with something like this. And the worst part is that, at least on the video game publisher side, some of them work perfectly.
I played a number of web browser ports of the games linked in the thread above, and some of them seemed to be borderline perfect. In the case of The Simpsons: Hit and Runmaybe it’s even better than perfect, because I don’t remember the game being able to aim for 240fps when I was a kid. It is also extremely concerning that one of the four different web browser ports of Halo: CE I played on working online servers…and my ping was low.
Look, I’m not happy to admit it, but it’s the truth – and it’s pretty simple too. Most games ported to browsers are titles from the PS2 or PS3 era. Do you know how much RAM the PS3 had? About 512 megabytes. Do you know how much memory my web browser is currently using as I type this? About 1200 megabytes.
Web browser ports have not been limited by RAM usage for some time. The difference here is that Claude Opus 5.5 is an AI that you can leave running overnight to decompile a game instead of painstakingly going through the code, like your grandfather did.
I don’t know where we go from here. All I can say for sure is that video game publishers’ legal teams are going to be working overtime for the foreseeable future.
