Modern generative AI is like a force of nature, it seems.Sometimes it does things that are good for us, like solving a 50-year-old grand challenge in protein folding.Other times, it might be bad for us, such as the environmental issues around data centers, or how it can supercharge malware.
Lately, it seems that video games (and all software, really) are in the sights of AI users.Thanks to the incredible coding power of AI, the world of video games on PC is about to get both more interesting, but also more chaotic.AI is taking some of the grunt work out of decompilation Finally, a good use for AI? Close You may have heard of game decompilation, where someone will take the compiled binary of an Xbox, PlayStation, or Nintendo game and then reverse it back to source code.
Once you've done that, you can alter the code just like any open-source project, and compile it as a native application for any platform you like.This is why we've seen a glut of games recompiled for other platforms by fans.There's even a dedicated launcher called Quiver that can track and manage all of these games on your PC.
The actual decompiled code is perfectly legal, since the original developer doesn't own any of it.It's the same rationale that makes clean room reverse engineering legal, as long as no patents are being infringed upon.However, you need to bring your own copy of the game's assets.
These are copyrighted, and so they can't be included with the recompilation.This is nothing new.The same is true for traditional source ports like In each case, you copy your asset files from your legally-purchased games into the right folders and the source port or recompiled game does the rest.
As you've probably already realized, this opens the same avenue for piracy as regular game emulation.However, since there is source code which can be openly modified, the community can do just about anything they want with these games.With an emulator running ROMs or disc images, there are only a few ways you can modify or enhance the game, and emulation has inherent performance and accuracy issues that a native piece of software doesn't.
If you look at the list of games on the Quiver website, you'll see each of them is labeled with a tag related to AI.It might say "Mostly AI" or "AI-assisted." This exists so users can know whether they are running vibe-coded software, but it's also a clear indicator as to why we're suddenly seeing all these decompilations; AI tools are accelerating decompilation so much, that almost anyone can do it.An unofficial port and a pirated game are different things A different path to the same destination? But I have to be completely clear here: recompilations are not piracy.
Just like emulation software is completely legal, as long as it does not contain any proprietary code.This is why original PlayStation emulators don't include the official Sony BIOS files they need to run.They leave that up to the user to provide.
Technically, you're meant to dump your own console's BIOS, but of course most people don't do that and simply grab them from the internet or from a friend.Piracy comes into play when you did not pay for your copy of the game data necessary to make the recompilation work.Putting it in the same boat as piracy via emulation.
However, the Digital Millennium Copyright Act (DMCA) brings another twist to the plot.It makes it illegal to create a copy of media you legally bought for personal use, if you had to defeat copy protection in order to make that copy.This is why it's legal to rip your music CDs to your MP3 player for your personal use, but it's not legal to rip your DVDs to a hard drive to play them using Jellyfin or Plex.
At least not where the DMCA is in effect.It's the defeat of the copy protection itself that triggers DMCA.Now, in the case of extracting assets from a game disc for use with a recompiled executable, you could argue that this does not run afoul of DMCA, because you did not have to crack the game in order to get those asset files.
I'm not a lawyer, and this idea is untested as far as I know.I'm just pointing out that there's a difference between removing something like Denuvo from a game, and copying a game's data files from one folder to another.Recomps might make emulators obsolete, but are they the better form of preservation? Thanks to tools like Reverse Engineer Anything, the game recompilations are going to come thick and fast, but where does that leave emulation? As someone who loves to play retro games on original hardware, I do think there's more to the experience of a game than simply the game itself.
Emulation tries to recreate the original hardware either through software or hardware emulation, with the latter being achieved using FPGA chips.A recomp is effectively a remake or a remaster.Yes, it's going to be technically superior, but I don't think it fulfills the same purpose or has the same spirit as emulation.
However, if the public decides that recompiled native ports of old games are simply better, then emulation development could stop overnight.Only time will tell.An even bigger issue might be that decompilation can be done for games that are released today, whereas emulation of consoles generally only becomes viable after years of work.
Come to think of it, the development of emulators themselves will now be accelerated thanks to AI.So expect publishers to target these types of software in any way they can.
