Umineko: When They Cry Saku: 3 Open Source Clones Compared
07th-Mod is not a game engine reimplementation but a cross-platform installer for the project's own fan mods for Umineko and Higurashi. The two actual engine ports target different releases of the game: Umineko Project's ONScripter-RU engine is built specifically for the PlayStation 3 port, while shin is a separate, newer reimplementation of the engine used by the Switch/PS4/Vita releases.
