I've done some more testing, and it seems Whip's gun has also been removed from the PlayStation version. Also, the blood on Chang and Choi in the Kim Team ending has been totally removed.
But, frankly, I'd only recommend the PS version for PlayStation owners on a budget (I got it for $10, new) or collectors interested in the extra features, anyhow. In my opinion, it just doesn't play as well as the DC version (with the exception of double half-circle motions going from impossible on the DC pad to just hard on the PS pad), and looks and sounds a whole lot worse. It's too bad that PS got the original Neo BGs, while I have to put up with the 3D ones on DC. Sure, they're pretty good compared to the sparse Dream Match 1999 BGs, but I still prefer the style of the 2D stages.
