NScripter is closed source. The author's terms text says so and that there is no plan to open it; the GitHub repositories NaokiTakahashi/NScripter and NScripter2 contain executables, DLLs, tools and manuals but no source or license file. The author's terms make NScripter free for free-distribution games, contest entries, magazine freeware/shareware and doujin sales, and charge 400,000 yen per commercially distributed work (negotiable) for works reviewed by a self-regulation body such as ソフ倫. ONScripter (GPL-2.0, ogapee) is an independent reimplementation that runs NScripter scripts; its README does not say whether the NScripter commercial terms apply to games run only on ONScripter. Agents should not treat the NScripter repositories as open-source dependencies. Rationale: Terms text, NScripter2 license page and ONScripter README were read. Counterevidence: The GitHub listing under the author's account could be read as an open distribution; the terms say otherwise for source code. Uncertainty: Whether the author's fee applies to games that only use ONScripter is not stated anywhere read.
