Harbour Masters expands beyond N64, begins GameCube PC ports

Harbour Masters is making the jump that decompilation fans have been watching for: the N64 specialist behind Ship of Harkinian is moving into GameCube PC ports, and that pushes native preservation work into a far more ambitious lane. The shift is bigger than a branding tweak. It signals that the tooling behind these fan releases is starting to stretch beyond one console generation and into a system with tougher game architecture, richer asset pipelines, and a higher bar for faithful PC adaptation.

The change surfaced on Harbour Masters’ Discord on May 31, 2026, where the group said it would eventually drop the “64” from its name and upgrade Libultraship, or LUS, so it can support GameCube-era games. The first project to use that expanded stack is Twilight Princess: Courage Reborn, a PC port of the GameCube version of The Legend of Zelda: Twilight Princess. Harbour Masters member Caladius said the project is being developed with Linifadomra and that support and development will move into the Harbour Masters Discord, while Linifadomra keeps creative freedom and Harbour Masters provides development help, long-term support, and visibility.

That matters because Harbour Masters already has a proven lane. Its site still describes the group as a maker of native PC ports of classic Nintendo 64 games, with support for arbitrary resolutions, ultrawide and multi-monitor setups, 60, 120, or unlimited FPS, controller support, mod loading, and Windows, Linux, and macOS. Ship of Harkinian, the team’s Ocarina of Time port, first landed on Windows in March 2022, and Harbour Masters now says its community tops 200,000 players. A move into GameCube gives that established pipeline a much wider reach.

The Twilight Princess groundwork is also unusually strong. The Zelda Reverse Engineering Team’s decompilation repository says the GameCube releases are completely matching, while making clear that it will not produce a PC port itself. It also lists supported GameCube versions GZ2E01, GZ2P01, and GZ2J01. Courage Reborn is separate from ZeldaRET and should not be confused with Twilight Princess: Dusklight, another project from a different group. Time Extension says the new port will target widescreen play, unlocked resolutions, unlocked frame rates, Mobile and Switch support, plus texture pack and mod support.

For preservation-minded players, that is the real story here. Harbour Masters is no longer just polishing Nintendo 64 classics for modern desktops. If its GameCube-capable LUS stack holds up, it could become the framework that lets more reverse-engineering teams turn console decompilations into playable PC releases without starting from scratch every time.
