Looks like the translation patch was removed from the base of translations. Why? Weak translation quality is the reason? Well, I completed the game using this patch 2 years ago, and it makes understanding much easier anyway. It's not good, but OK. Other weak translations, like Hoshi wo Miru Hito, are still in the base.
I think that's cause no effort was made to do anything about the Google Translate-y nature of the patch. According to the site rules machine translation can be used if you fix the text afterwards. I recall that not being the case here, so that's probably why it was removed. There are a few patches like that, like the old Villgust NES patch for example. Well, maybe someone will make a better patch someday.
