Moonlight Syndrome English translation
ムーンライトシンドローム
A playable English patch for Suda51's cult PlayStation horror adventure Moonlight Syndrome, covering both discs and all ten chapters, built on the fan translation from a 2023 video series.
What's translated
The patch covers both discs and every chapter, from the prologue to the epilogue: dialogue, choices, speaker names, save prompts and a clearer chapter select. Scenes that were only voiced get timed English captions, including the ending call and song, while the Japanese voices and the original staff credits are kept. A few decorative Japanese graphics remain.
Where the script comes from
The main script is Jolovey's human translation as shown in Paradise Hotel 51's 2023 video series, which itself grew from an earlier draft by Izzeybee. Quessada House turned it into a playable patch, using AI-assisted tools for the reverse engineering, programming, speech recognition and for optional lines missing from the videos; those extra parts have not had a full Japanese review. Jolovey has since revised his translation for a separate project, which this patch does not include.
Playing it
There is one patch per disc, applied to your own unmodified Japanese discs following the instructions on the official page. It was played through on DuckStation. Version 1.0.1 only expands the in-game credits.
