Unfortunately I am not sure who the developer is, but am wondering if Yukio/nyanchan might be able to hlep here. Maybe it's just a temporary thing that will be sorted in a couple of weeks or a month or so.

You can find his contact info, or at least you can e-mail him using a link on Galaxy Laboratory's website. Go to the site, then click on 総合掲示板. Any post written by ☆shiningviolet should contain a link at the end to e-mail him. If they don't, just write a post. To do that, click on the post link, and enter a name (you don't need to set up an account). Just type something in the name edit box. It can be english or japanese, language doesn't matter. Next comes the actual post, and this might be hard. If you know Japanese, just write the post and click on the post button at the bottom. If you don't know Japanese, write the post in English or any other language in a document and put it through Google Translate as English to Japanese. It won't be perfect, but it's usually clear enough for the people who read it to understand it. If you're doing it through Google Translate, translate your post first, copy it to the clipboard, then go to the 総合掲示板 on Galaxy Laboratory and follow the steps starting with entering your name. The same works for Morokuma's Text Game Bullitan Board.

What I mean is that ☆shiningviolet, who posts on Galaxy Laboratory, is the developer of those games and that link you put in the first post is to his website. So, maybe you or someone could post on Galaxy Laboratory's website and ask the question to him, as long as you follow the instructions I put in post 5 because he doesn't speak English. Or, at least I don't think he speaks it.
