Since it was released years ago on the PS1 I thought maybe there were some sketches and/or settings made for the animated sequences that were in the game. I search YJ almost every day looking for anything like this with no finds so far.
On another note, I feel like I gotta flame a little bit. I bought some character settings a few months back from Xenogears (another game I love dearly), but I'm VERY skeptical about the authenticity of them. I really believe the seller made copies and is selling them on YJ claming them to be actual production copies. My copies are 'brand new', not one single crease, dirt smudge, no scribbles or writings, nothing! They were crisp and clean papers plus the picture quality on them are low IMO, meaning they look as though they were copied from copies. I paid almost $100 for them with deputy service fees included. After winning them, the very next day the seller placed the exact same settings for sell again! Then I thought, was this guy ripping me off, was he re-selling the item I just bought and I won't receive it? So I contacted Rinkya and asked if they could look into this since I thought something was fishy but they replied telling me that I was going to get what I paid for and most likely the seller had multiple copies of the game settings for sale, sorry but YEAH RIGHT, sure, multiple copies. This is the only time I have ever felt ripped off on a YJ auction. If anyone can prove me wrong on my theory, please let me know so I can feel some comfort. Maybe I should have purchased the Xenogears Perfect Works artbook instead. At least I could then view the artwork much more clearer than those horrible settings I have now.
Thanks for reading.
Luckily I didn't pay anywhere near $100, but still, it really bites. 
I see 2 sellers selling settings again for Xenogears. This is the same seller who is selling an exact same copy of the setting that I won with crappy clarity (at least mine were).
