PS1’s Obscure Mermaid RPG Meremanoid Just Became a Battleground Between AI and Human Translation

There’s a special kind of drama that only the retro fan-translation scene can produce. On Friday, someone released an AI-translated English patch for Meremanoid — a 1999 Japan-only PlayStation mermaid RPG that roughly none of us have ever played. Before the weekend was even over, one of the scene’s most respected names had popped up with a warning: ignore it. The real thing is coming.

For the unfamiliar — and I’m going to assume that’s nearly all of us — Meremanoid is a genuine oddity. Xing Entertainment’s 1999 PS1 RPG featured character designs by Akihiro Yamada (the Twelve Kingdoms illustrator) and a story by Kenji Terada (yes, that Kenji Terada, of Final Fantasy fame). You play Arden, an androgynous blue-haired amnesiac with a mysterious ring, in a world almost entirely populated by women — exploring, shopping, meeting NPCs and fighting through turn-based combat in a fully ocean-themed setting. It was apparently even preceded by a TV anime from Kitty Films and Triangle Staff — a multimedia rollout that still wasn’t enough to get the game an English release. Xing, for the record, spent the 32-bit era publishing PlayStation ports of arcade curios like Irem’s In the Hunt and Taito’s Pu•Li•Ru•La, so Meremanoid sits squarely in their wheelhouse.

The Friday patch, from a hacker going by pzappzap, claims “all of the game’s text is translated” — while disclosing in the same description that the translation was produced with “CODEC BABEL’s AI agents.” So: a machine-translation patch, honestly labeled, for a game whose entire narrative hinges on nuance.

That’s when fan translator Cargodin stepped in, and the response is worth quoting at length: “Please ignore the MTL release of Meremanoid that came out today,” Cargodin wrote. “We have had a hearty band at work (Chapu, Popi, Mr. Nobody, Misty, Shentok and I) working hard on an all-human patch. Fully playable in English, in its final editing pass now.”

The reason matters more than the drama: “This game is set around a matriarchal ideocracy that uses presented gender and one’s ability to conform as excuses for xenophobic conquest and religious warfare. Pronouns and who uses them when are half the narrative, and an MTL could NOT bare this game’s fangs correctly.”

That’s a genuinely good argument against machine translation — not vibes, but a craft problem. When a story is literally about gender and pronouns, a machine guessing at nuance is a structural hazard.

The lineup is worth noting, too: it includes Chapu — a name regular readers may recognize from the Chapu Translations crew behind the “absolutely human-made” Schrödinger no Neko patch we covered earlier this month.

And if this feels familiar, it should: a week ago we covered Saralene’s complete human-made Air Management ’96 translation, released specifically to make an “insulting” GenAI patch obsolete. The playbook is repeating — human translators treating an AI patch as a bug to be fixed, not a solution to be applauded.

To be fair, the AI patch’s machine-translation method was disclosed upfront by its author, and nobody’s claiming bad faith. But disclosure doesn’t fix quality. I’ve waited decades to play Meremanoid in English — I can wait a little longer for the version made by people.

The AI-assisted patch’s machine-translation method was disclosed by its author; the all-human patch’s status comes from Cargodin’s own statement as reported.
