The PS1 wasn't half-bad. Sure, most stands got only one color and some sprites were removed, specially the blood and Jotaro smoking poses. But most of the action was still the same and it got the Super Story Mode, with extra characters, more mini-games (including a card game) and many other stuff. I recommend the Arcade version better, through, but if it's easy to you to get the PS1 version running it isn't a big loss.
