So I come home and play the game:
Backgrounds:
The BGs are in full 3D now. There's a option to change it to NORMAL (3D) and ARCADE (2D).
Korea: The city back there have some life now. There are cars passing by the bridge, the birds are 3D (although they keep flying like flies over a trash can in the middle of the BG), and there's airplanes constantly flying near the great tower. That tower have two elevators going up and down. This BG is the most pretty one at his night version. Maybe SCEA wound't like these airplanes flying too next to the tower...
Japan: Don't have significant changes at all.
China: When the red gates are closed and Bao is at the middle of the BG, the red gates open for a while.
Holland: The windmill are nice, and three ballons are moving in the sky to all directions. There's more grass in the ground too.
Camboja: There's MUCH more trees, and the shrine back there is 3D and bigger than your 2D version. The stones in the ground have better details, since it are 3D now.
Mexico: King is out of this BG, since she's fighting now. The TV screen showing Heidern is a little more nitid image. There's a SNK PLAYMORE logo up in the center of the stage, above the wood bridge. In the night version, the torch in center is more brighter, but still 2D.
Italy: Almost full 3D now, you can see all things below the elevator's floor. There's chains in the left swinging with realistc movements, and all the gears are polygonal made. There's a pathetic camera man too...
SkyNoah - Cockpit: The damaged cockpit of SkyNoah, Rugal's airplane, having monitors and computers all over the place. There's ladders leading to the 2º floor where the windows are broken, making the wind blows strong into the cockpit and making a lot os papers fly quickly to all directions.
SkyNoah - Hangar: Now we know how the chars manage to escape from SkyNoah's self-destruction: the helicopter used by Heidern to escape is here and the door is open making some BG's objects be sucked out of the airplane (boxes, oil drums, cars, and even militar tanks!).
Strange... There's no 3D version of Rugal's stage?
Music: There isn't AST tracks... Only the same from MVS version...
Extra chars: The same from DC port (Shingo and King), plus Geese, Goenitz and Orochi Iori. You must play the CHALLENGE mode (divided in Team, Single and Time Attack) to unlock them. My friend
Kododis unlocked Geese, Goenitz and Orochi Iori in Team Attack, and I unlocked Shingo in Team Attack after beat 18 teams.
The artwork of Geese and Goenitz in the Player Select screen is a shame. Someone trying to copy the original artist's style., I guess...
These chars are ripped of from SvC: Chaos
directly. No surprise, but even in the original game they're over powered...
Graphics: Not much to say. The special moves have the same effects of the SvC Chaos, but the chars not. I mean, they're "over pixelated"... There's a option called GRAPHIC, where you can choose the SCREEN to TYPE A (normal) or TYPE B (large), but in TYPE B the chars become too pixelated, and the 2D people in BGs even worse, so all of you probably will sticky with the TYPE A mode.
EDIT: The gameplay is intact, and the load times are longer than 2000/2001, but not annoying.
