Oriental Legend 2 Character Unlocks

I'll probably never get an answer on this one, but figured I'd post it here just in case. Does anyone know how to unlock the priest and spider-girl type characters in Oriental Legend 2?

Sorry to break it to you man, but there isn't much gameplay discussion in this forum. You surely won't find any PGM gameplay discussion in here either.

There are some PGM2 owners here, but you'd have better luck of them seeing this posting it in Arcade central.

I have Oriental Legend 2 and as far as I know, the only way to play as those 2 characters is to start a new character using a "memory card". If you don't have a card reader to use with your mobo, it may be impossible. There might be some code, but I've never seen mention of it. But then, English language info on this game is scarce.
