I seem to recall reading somewhere that there is a small list of PSOne games that don't seem to be compatible with PS2 hardware (and I also recall Castlevania being on that list). I was able to find two new copies of SOTN at a local hardware store (of all places!) and was going to sell them on eBay if the prices were high enough. They are currently selling for around $20.00 new, so I'm going to return one of them and keep the other for myself. However, I will be returning both if this game doesn't run well on the PS2 hardware. Has anyone had any negative experiences running this game on PS2 hardware?
