I think those pics are from the SegaCD version. I've been wondering for a while what the game looked like. I tried burning that a few days ago but I couldn't get it to work *hits scdconv*.

I have an ad for it, here's a link. I scanned it a while ago and it's just kicking arouns on my webspace.
yeah those pictures are 100% from the Segacd/MegaCD version (I own it so I should know)

and by the way this game works on PAL megacds as far as I know but on US I don't know
Thanks for the ad, ragnar. Damn, why the heck does it have to be in Japanese? Why don't they port these farkin' games!?
