Ocarina of Time PC Port Developers Reveal Years of AI Use, Sparking Fan Outrage Over ‘Vibecoded Slop’
Harbour Masters, the talented group of modders and developers behind the beloved reverse-engineered PC port of the classic game, the Ocarina of Time, has recently found itself in hot water. They’ve been accused by some in the gaming community of utilizing AI-driven tools to create, code, and modify their various ports of iconic Nintendo titles. While the team acknowledged that some members do use AI in their workflows, they firmly rejected claims that their ports are merely “vibe-coded” or filled with “AI slop,” asserting that every line of code is meticulously reviewed by skilled developers. This response, however, did not sit well with all fans, leading to a wave of online backlash.
Discussions among retro gaming enthusiasts about Harbour Masters’ use of AI tools like Claude have been circulating for several days. The situation escalated on September 16 when a post on a community wiki went viral, alleging that thousands of lines of code across multiple ports, including their well-known Legend of Zelda: Ocarina of Time port, were generated with AI assistance. This post gained traction on social media, particularly after being shared on various platforms.
In the wiki post, a user named “Slopiskillingretrogaming” claimed to have uncovered evidence that Harbour Masters’ ports contained significant amounts of AI-generated code and assets. They stated, “Harbour Masters has shifted into using ridiculous amounts of AI-generated code and even some assets recently, and their projects arguably do not meet the requirements of the PC gaming wiki anymore.” They specifically pointed to the runtime component called libultraship as being particularly affected, suggesting it was also used across individual ports.
The user further alleged that the team was attempting to obscure their AI usage by removing co-author credits. They provided numerous code snippets that they claimed demonstrated the involvement of AI tools, including direct references to Claude. The post also suggested that recent code changes showed signs of AI influence, allegedly coming from the lead maintainers rather than random contributors. Additionally, it was claimed that some images used by the team were AI-generated.
The wiki post quickly spread among retro gaming fans, sparking intense reactions. Many players who had enjoyed the team’s ports expressed disappointment over the apparent use of AI tools without proper disclosure. This frustration led some fans to join the team’s official Discord server to voice their concerns.
Inside the Discord, it was evident that the team was taken aback by the wiki post and its fallout. Many members of Harbour Masters vehemently denied the claims, labeling them as “total lies” and “highly untrue.” One of the key allegations was that millions of lines of code were created using AI, but developer Malkierian clarified that a significant number of functions were “converted using a script developed with the assistance of AI and tested for parity afterward.”
Despite this clarification, it became clear that Harbour Masters does incorporate AI tools into their development process. Developer Briaguya addressed the concerns, explaining that while the team has always been committed to quality, they have also utilized AI for problem-solving and coding assistance. “People saw Harbour Master projects being built by passionate developers in a non-slop way and assumed that meant that none of the devs had talked to ChatGPT about a tough problem or used GitHub Copilot,” Briaguya noted.
The team emphasized that they thoroughly review all code, regardless of its origin, to ensure it meets their standards. They also pointed out that they have had a publicly available AI policy for months, which they plan to expand. This policy stresses that all code undergoes human review, with team member Dana the Elf reiterating, “We don’t just use generated code – our contributors have used LLM conversations to work through a technical problem, or to iterate through something and put their ideas into code that is then verified by human eyes.”
All team members made it clear that they do not use or support AI-generated images and have no plans to do so in the future. They argued that embracing AI tools is simply part of the evolution of development.
Developer Jeod provided further context, explaining the team’s small size and heavy workload. “One of the reasons I think we are accepting of AI contributions is that our developers are spread thin,” he said. “When Ship of Harkinian began, it was a dream; now, with so many ports and a decade later, devs have come and gone; some don’t have interest in specific games, others have real life to deal with.”
When asked about which version of Ship of Harkinian was free from AI-assisted code, developer Briguya candidly replied, “I don’t know.” He acknowledged using ChatGPT as a resource but couldn’t pinpoint specific instances.
For many in the community, the revelation that Ship of Harkinian is being developed with AI tools was disheartening. The confirmation of Harbour Masters’ use of these tools in their ports made the recent release of their latest PC port, Paper Mario, feel somewhat awkward, leaving fans uncertain about the extent of AI involvement in that project.
