At the moment, it is far to early to give any estimates of when the patch will be done. All I can say is that it'll be done when it's done. Trust me, I want this patch maybe more than anybody else, but these things take time. It's best to be patient, check the thread occasionally, and just accept it.
Everybody involved in this project, myself included, has a private life in the real world that they must attend to first. Some of us also have other projects that they're working on, so I hope you can understand when I say that we can't devote 100% of our time to making a translation patch for such an obscure game.
On another note:
The translations for the Prologue is complete, and Akihisa Yoshii's storyline is almost complete. That said, we will not be releasing a patch until the entire game is translated. I don't want to jeopardize the project by release an incomplete patch and having it distributed. It would also make debugging quite a pain, making sure that people are running the same version and whatnot. If, for some reason, this patch ever does get cancelled, I plan to release all the translated resources and scripts. But let's hope it doesn't come to that. Anyway, work is continuing at a steady pace, so I'll be sure to keep you guys posted about our progress.
