On a related note: It turns out that machine translating the Wolf RPG Editor base system is relatively easy, thanks to the editor's robust import and export functions.
I may write a script and translate all the contents one of these days, though I've heard there a japanese guy working on his own english translation of the base system, something I would not want to impede. Still, the possibility's there, if anyone else wants to take a shot at it, feel free to do so. I recommend Claude Opus for AI translations, though the translation in the image has been made by gemini-2.5-exp (latest).
Together with the already existing english translation of the editor itself, a fully translated UP-TO-DATE version may be released somewhat soon.
