@encounter, the founder of decomp.dev—a community that served as a forum for exchanging information on “decompilation,” such as game reverse engineering and code organization—announced that the community is ceasing operations.
Even “Legal” Decompilation Communities Cannot Prevent Cases of Abuse
The community, which has been active since 2024 with the aim of sharing decompilation information, served as a space for understanding game mechanics and conducting research while respecting the original works.However, according to this announcement, due to the recent rapid advancements in AI technology, the community—which is fundamentally based on open source—is unable to prevent cases of misuse, and therefore plans to phase out its services.
In the announcement, the community acknowledged that in the past, AI-assisted decompilation often inherently involved obvious issues or misconduct, and when factoring in the necessary corrections, the cost per task was significantly higher than usual. However, they stated that they have determined recent AI models possess the problem-solving capabilities to completely transform this situation.While acknowledging the usefulness of AI in significantly accelerating the decompilation process, the announcement noted that instances of use contrary to the community’s philosophy—which has long been dedicated to encouraging contributions and benefiting the community as a whole—are already becoming prominent.
Skipping the Process of Ongoing Projects and Unilaterally Releasing a “Completed” Version
As prime examples, they pointed out cases where AI-generated, completed versions of projects are announced as “derivatives” of ongoing projects, as well as the rampant practice of so-called “unauthorized ports” that utilize decompilation results.Not only do these instances involve absolutely no contribution to the original decompilation project, but in many cases, the quality of the resulting output is not verified either; the community firmly asserts that these actions undermine its very foundation.
He also stated that decompilation within this community has traditionally been positioned primarily as a research activity, and made it clear that he has worked to establish this framework.While expressing his view that the focus has been on understanding the inner workings of original works out of respect for them, he also voiced concern that in recent decompilation communities—including on Reddit—the term “decompilation” itself is being used to mean “PC port.”
He made it clear that replicating the site is not permitted. He also stated that AI itself is not the problem.

He stated that this decision was reached after synthesizing these opinions and concluding that decomp.dev had become increasingly prominent in perpetuating the negative aspects of this trend. While the addition of new projects and indexing has already been disabled, the tracking of existing projects, individual project pages, and historical data will continue to be provided.
Furthermore, they clarified that decomp.dev itself has never been open-source and that @encounter retains the rights to it, stating that they do not permit any reproduction.Regarding the suggestion that AI-powered projects should simply be banned, he stated, “AI itself is not the problem; when used correctly, it can be extremely helpful,” while also noting that defining and managing what constitutes “good” or “bad” use is extremely difficult.
In the gaming industry, as seen in this case, while concerns about misuse persist even within existing communities, there are also aspects where AI is viewed with high expectations as a mod-creation tool—suggesting that the debate has not yet caught up with the pace of AI’s development. While improvements in technology and legislation are certainly expected, it seems we are living in an era where users’ ethical standards are being put to the test.
