Zelda and Banjo Recompiled Developers Confront Wave of AI ‘Slopcomp’ Ports

The developers behind the acclaimed Zelda: Recompiled and Banjo: Recompiled projects have publicly distanced themselves from a growing wave of AI-generated decompilations, condemning what they call “slopcomps” that threaten to undermine years of careful human-led emulation work. The backlash intensified last week when a project titled Banjo-Tooie Recompiled surfaced online, drawing sharp criticism for allegedly corrupting established PC porting efforts with AI-written code.

The controversy centers on the fan-made N64: Recompiled tool, an open-source utility that has enabled enthusiasts to reverse-engineer classic Nintendo 64 games for modern hardware over recent years. While this community-driven approach produced polished, playable versions of beloved titles, it has now attracted a new breed of contributors using AI “vibe coding” techniques—generating code through natural language prompts rather than traditional programming expertise.

A Clear Line in the Sand

DarioSamo, an Argentinian software developer who contributed to the human-led unofficial port of the original Banjo game, publicly called out the channel behind the competing project for failing to disclose its use of artificial intelligence. He emphasized that both major Recompiled projects maintain strict anti-AI policies and have never relied on generative tools.

The Banjo-Tooie Recompilation is NOT associated with us. It is entirely AI-generated. Both Zelda: Recompiled and Banjo: Recompiled have very clear No AI stances. We have not, do not and will not use AI to ever work on these projects.

Samo continued by explaining that his team had already announced plans to port Banjo-Tooie at some point without any AI assistance. He stressed their commitment to quality over speed, noting the extensive human research invested in building frameworks, renderers, and game code.

We’re not interested in engaging a race to the bottom and will take the time that is necessary to deliver a polished version of the game. Using the extensive amount of human research we’ve done for the framework, the renderer and the games themselves and throwing AI at it is just disrespectful.

The Community Pushes Back

The frustration extended beyond a single developer. X user FunkyLion, known as Yuyake, took to social media to condemn what he described as untested, buggy ports created by inexperienced users. He pointed out technical concerns about the competing project’s approach, arguing it would harm long-term maintainability.

Worth noting it’s also one of those slopcomps that completely ignores the existing patching system and instead opts for patching all of the recompiled code and memory from the wrong side, meaning modding as people usually expect it is completely unmaintainable in the long run and it contributes nothing to the decompilation efforts.

To combat the proliferation of AI-assisted projects, FunkyLion created a curated list documenting decomps and recomps completed by actual people. He argued that these human-made efforts deserve recognition rather than being overshadowed by inferior alternatives.

Now we’re in the mid-2020s, and AI has gotten a hold of everything, with people that have little to NO programming experience porting games completely untested, leading to a wave of buggy AI ports of games that are completely broken. And the sad part is, they overshadow the quality work of decomps/recomps done by actual people.

Broader Industry Concerns

The debate over AI in emulation has reached beyond individual projects. Jay Gunn, a developer working on a new MediEvil recompilation project, voiced his support for the backlash against slopcomps during an October 1 discussion.

I have no idea about what this is other than what I see posted here. But I agree with what the comments are saying – keep GenAI the fuck away from MediEvil… now and in the future! The charm of those days of dev’ was that everything was hand made with barely any premade tools or shortcuts.

The controversy arrives amid a broader reckoning within the gaming industry regarding generative AI. Publishers including Activision and Bethesda have reportedly issued legal notices to developers working on GenAI-based projects, signaling that the tension between open-source emulation communities and corporate interests is intensifying.

Looking Ahead

As the community continues to grapple with these issues, human-led decompilation efforts remain committed to their anti-AI stances. Developers like DarioSamo insist they will take whatever time is necessary to deliver polished results rather than rushing products to market.

The Banjo-Tooie Recompiled project has faced mounting pressure to address concerns about transparency and technical approach, with community members calling for it to be renamed or reworked. Whether the wave of AI-assisted ports will continue or subside remains uncertain, but the established decompilation community shows no signs of abandoning its principles.
