Well I bought the wii version when it came out, the boss thing is kinda annoying but really I could give a crap less about the D-Pad thing.. It's metal slug.... common people it was meant to use a stick. I bought it mostly for MS6 as I have 1 and X on playstation and 3-5 on Neo Geo. For $40 it was a steal, and I play it with a wavebird controller.

As for the PS2 version I'd wait a few days before believing everything was fixed. I don't think SNK/Playmore has ever put out a perfect game, why would they start now.
