AI can help make some decompiler output easier to understand, but it cannot reliably restore a commercial game’s original source code or turn a binary into a faithful, rebuildable project. Whether examining or sharing that output is lawful depends on where you are, how you obtained and accessed the game, your purpose, the applicable license, and what you do with the results. There is no universal legal answer—or established success rate for AI decompiling complete commercial games.
What does it mean to decompile a video game?
Decompilation translates compiled program code into a higher-level representation, such as pseudocode. A conventional decompiler works from instructions and whatever metadata remains in the binary; it does not retrieve the developer’s original project files.
That means the output generally cannot restore the original source tree, meaningful variable and function names that were stripped, comments, assets, level-authoring files, or the build pipeline. Even when the result looks like source code, it may be incomplete, difficult to compile, or behaviorally different from the original.
“How do you decompile video games just in general?” is really several questions. The technical approach depends on what you have: a native executable, managed bytecode, separate scripting files, or assets. It also depends on the platform and any protection scheme. Decompiling program code is not the same as extracting assets, and neither automatically reconstructs a complete game project.

What can AI contribute?
AI can help interpret or refine output from conventional analysis tools. The 2024 paper LLM4Decompile: Decompiling Binary Code with Large Language Models describes model-assisted binary-to-high-level-language recovery and refinement of conventional Ghidra output. Its results concern the models and benchmarks reported in that paper; they do not demonstrate reliable restoration of arbitrary commercial games.
In practical terms, an AI-assisted workflow may make a function’s logic more readable or help an analyst form and check hypotheses about what a piece of code does. That is useful for understanding behavior, but it is not proof that the inferred source is the original or that a replacement will act the same in every circumstance.

Why readable or compiling output is not proof of a faithful game
There are three different quality questions: can a person follow the output, can it be compiled, and does it behave like the original? Success on one does not guarantee success on the others. A function may compile and pass supplied tests yet differ for other valid inputs.
A September 2026 paper, When LLM Decompilers Recompile More and Preserve Less, reports 4.9% overall divergence among candidates that passed every shipped test on the study’s evaluated input corpus, and up to 13% for one system. Those figures describe the paper’s systems and corpora—not a universal error rate, and not a video-game-specific rate. The authors propose comparing behavior with generated drivers and expanded fuzz inputs, illustrating why tests bundled with a program may not cover all relevant behavior.

The sources cited here do not establish a representative success rate for reconstructing complete commercial games. A function-level benchmark cannot establish that an entire game—with its code, assets, data, dependencies, and build process—can be restored as a faithful, working project.
How to approach analysis without mistaking it for restoration
- Define the question. Decide whether you need to understand behavior, investigate interoperability, study security, preserve a game, make a mod, or build an independent replacement. The goal can affect both the analysis and its legal treatment.
- Identify what you are examining. Establish whether the material is native code, managed bytecode, scripts, or assets, and note the game version and platform. Different targets expose different information; none alone promises a recoverable original project.
- Keep the original intact. Preserve the binary you are authorized to examine and document the tools, assumptions, and changes used during analysis. Treat generated source-like output as an interpretation, not a substitute for the original.
- Check behavior, not just appearance. Compare the inferred logic against observed behavior and use tests broader than any shipped test set. Passing a limited suite or compiling is not proof of equivalence.
- Resolve permissions before acting or sharing. Check local law and the game’s license or contract before circumventing protections, using derived material beyond private study, or distributing code, assets, a playable build, or a replacement service.
Is decompiling a game legal in the United States?
It depends on the facts; decompilation is not categorically lawful or unlawful. Copyright, anti-circumvention rules, contracts, and potentially trade-secret law are distinct issues. Relevant facts include whether you lawfully obtained the copy, whether you bypassed access controls or encryption, why you analyzed it, what material you copied, the license terms, and whether you kept the results private or distributed them.

The U.S. Copyright Office says: “The Digital Millennium Copyright Act (DMCA), codified in part in Title 17, section 1201, of the United States Code, generally makes it unlawful to circumvent technological measures used to prevent unauthorized access to copyrighted works, including copyrighted books, movies, videos, video games, and computer software.” See the Office’s 2024 section 1201 proceeding and the statutory text of 17 U.S.C. § 1201.
Section 1201(f) provides a narrower reverse-engineering provision. Among its conditions, a person who lawfully obtained the right to use a program copy may circumvent a protection measure for the “sole purpose of identifying and analyzing those elements of the program that are necessary to achieve interoperability of an independently created computer program with other programs”. The provision has statutory conditions and limits; it is not general permission to bypass a game’s protections for any mod, preservation, or replacement project.

In Sega Enterprises Ltd. v. Accolade, Inc., 977 F.2d 1510 (9th Cir. 1992), intermediate copying to discover functional requirements for compatibility could qualify as fair use in the circumstances. That case does not settle the outcome for every game, purpose, license, or jurisdiction. Cornell’s reverse-engineering overview also notes that contractual and trade-secret questions may arise.
Limited U.S. exemptions for certain game activity
The Copyright Office’s 2024 rule includes specific exemptions for certain lawfully acquired games. One covers restoring personal local play when the rights holder has ended required external-server authentication. Other provisions allow qualifying libraries, archives, or museums to undertake preservation activity under detailed eligibility and use restrictions. The current listed exemptions are in 37 CFR 201.40. They are not blanket permission to distribute a circumvention tool, game binary, or replacement server.

The UK has a specific statutory decompilation exception, not a general right to copy a game. Under section 50B of the Copyright, Designs and Patents Act 1988, a lawful user may decompile a program when necessary to obtain information needed to create an independent program that interoperates with it or another program. The permitted purpose and use of the information are constrained; the exception does not authorize reproducing protected expression or distributing a decompiled game.
Why sharing the output changes the questions
Private technical study, publishing a description of observed behavior, releasing decompiled code, distributing copied assets, and offering a playable replacement are not interchangeable acts. Sharing can raise additional questions about copyright, circumvention, license terms, and the purpose and scope of the material used. A rule that may apply to a narrow interoperability or preservation activity does not automatically authorize public distribution or commercialization.
For a real project, check current law in the relevant jurisdiction and the specific license terms, and get advice from a qualified lawyer if the stakes warrant it. The U.S. and UK rules described here should not be extrapolated to other countries.
