The PS2 port is a lot better than the DC version, here are the only problems found with the PS2 port:
-the words GUARD CANCEL not showing up on the screen when it happens -in training mode when you activate counter hit mode, certain special moves not launching the opponent like they should from a counter hit. -1 hit then block feature, not being able to super them like you should be able to from the 1 hit stun. -timings on certain moves different
Besides whats posted on the list everything else is pretty much intact with the arcade version. There are some added features also like random select in VS mode, not possible in the AES or DC versions.
