You should play it Ratty, I have the PS1 and PS2 versions around (PS2 via Street Fighter Alpha Anthology), the PS1 versions nice, but is missing some key animations (like knocking your opponent around the world, one of the games best animations IMO). I do want the Saturn version in my collection, especially when I found out some of the Darkstalker characters had renames when the series came to America. Lei Lei was one, and I prefer this name to the one Capcom gave her in the west. Hsien-Ko doesn't necessarily roll off the tongue as well as Lei Lei does, and especially now that I'm starting to want to get into Darkstalkers, and because I'm also on a heavy Capcom fighting game fever craze right now.
Plus the Saturn version of Pocket Fighter has voice acting for the ending, but sadly not in English, doesn't matter though as the game is very charming.
