Just checking the threads, it looks like the two links are still up for those. I don't believe there is a translation though, and not much of a need for a walkthrough for those. I only checked to see if the pages were still working though, didn't redownload anything.This post is probably dead, but does anyone have a link to their previous works? Like Funka no ken or erotic? And if they have any english translation or walkthrough?
