decomp.dev Pulls the Plug on Its Public Index as AI Slop Breaks the Community

Some scoreboards just aren’t worth keeping anymore.

decomp.dev — the 2024-launched tracker that turned matching decompilation into a spectator sport, complete with progress bars and leaderboards across dozens of classic games — announced Thursday that it’s sunsetting its public layer. Effective immediately: the main index is gone, new project submissions are closed, and the central leaderboard is history. Existing projects keep reporting progress, and their individual pages and commit histories stay online — finished landmarks like Super Smash Bros. Melee and Animal Crossing among them — but the public scoreboard is done.

And the pseudonymous administrator behind it, who goes by Encounter, isn’t mincing words about why. In a statement titled “Sunsetting decomp.dev,” he says flatly: “the community aspect of decompilation has been broken.”

The culprit, per Encounter, is AI slop. Frontier models — “GPT-6-Astra”-class, in his words — have made decompilation trivially easy. Historically, he writes, matching decompilation was “a brutally difficult, time consuming task, on the scale of years for any moderately-sized game with a number of active contributors.” He grants that with the right guidance, human input and code reviews, AI “can expedite the decompilation process in a significant way.” But bad actors, he says, have been abusing that power: forking human-led projects to “finish” them with AI, racing original teams to release half-baked ports just to claim credit, and flooding the tracker until it’s become impossible to tell human craft from machine output.

Sound familiar? It should. This is the same fault line we’ve been covering all month — the human-led Beetle Adventure Racing decomp taking on an LLM-assisted recomp built on its team’s work, and fan translator Saralene rebuilding Air Management ’96 by hand to make a GenAI “patch” obsolete.

Here’s the nuance that deserves credit: Encounter isn’t calling for an AI ban. Banning AI-assisted projects is out — “slop” is “hard to define, and even harder to moderate,” as he told Tom’s Hardware, and one hobbyist can’t judge hundreds of projects. His problem is what the leaderboard became: “folks who just want to burn tokens to make number go up or ‘port game to PC,’ all else be damned.”

That line honestly guts me. A tracker built to keep volunteers motivated through every fraction of a percent of gruelling work is locking the trophy case because the score became the only thing anyone cared about. Encounter even wrote that nobody may reuse decomp.dev’s code to build a replacement — code he notes was entirely human-written.

So where does that leave preservation? The individual projects live on, the workshop doors stay open, and the human decomp teams keep grinding. But the community’s central scoreboard is gone — a casualty of the trust AI slop destroyed. What’s your call: is AI a tool for preservation, or a wrecking ball for the people doing the preserving?
