Great news for everybody! I've found a webpage where you can download Hakujaden in its entirety. This should be the real deal, not "Panda and the Magic Serpent." I've added the download link to the Downloads section, and all you have to do is scroll down the page to the four Rapidshare links. I'm working on downloading it myself, so I'm looking forward to seeing this.
This Hakujaden should be in its original language with English subtitles. Enjoy!
