Shaka, play DXC- it's worth it for the original Dracula X and you're not missing out on any of the awful, cheesy voice acting from the original version.
And why is someone just telling me now that the dxc version doesn't have Saturn areas and enemies when I swear I went through entire areas I had never seen before in the psx version? I remeber people swearing it did have new content beyond Maria.
It was pretty common knowledge that the extra areas and content from the Saturn version wasn't included in the PSP port, because Iga didn't work on it and refused to have anything to do with it, as Oscar already mentioned. IIRC this was mentioned in interviews when the PSP game came out.
I have the Saturn version and agree that it's not worth bothering with, due to the awful performance issues. Just check out the content and listen to the (awesome) music on Youtube. IIRC there's also new music for Maria...jazzy remixes of older CV themes.
