It is kind of ironic how so many comments said they needed RHDN to stay around to keep track of translations of games that never left Japan, but most PC-98 translations were never allowed there to begin with. RHDN was never suitable for all translations despite what many apparently thought.
Actually, now that I think about it though, it always felt a little weird to me. Most translation files don't themselves contain any explicit content, other than strings of course. You don't need to include explicit screenshots for those games, and it is not like the content of the games themselves are hosted on site, right? So why ban them? SEO is my guess, but I don't really know.
Thank you for your work by the way, you are giving these games a new life outside Japan.
