Forum:Tale Fantasia Manuscript

Tales of Phantasia was based off of an unpublished novel by Gotanda Yoshiharu called Tale Fantasia. I've looked and looked, but have found nothing more about it than a few differences between the game and the book.

I'm trying to find a manuscript (Japanese or English) of this work. Everything I've read calls it "unpublished," so I am assuming it remains that way even today, but there is information about it on the internet that makes me think it may have been released.

I would very much like to find it (and might could get it translated), but so far I have found nothing. Does anyone know of any leads that I might follow?
