There were two revisions with major differences released for the arcades: Rev. 990512 and 990608. 990608 fixed a minor bug(the one where the game resets if Ken beats Makoto with neutral throw) and removed unblockables, more specifically Urien’s and Oro’s, and is not played by anyone who is remotely serious about the game.
Dreamcast uses 990608, SF Anniversary Collection uses 990512. Both are not arcade perfect, though SFAC has been widely preferred due to the revision it uses.
3SOE uses 990512 WITH Ken&Makoto throw reset bug fixed.
I was playing the Xbox version for 3 days and decided to hook up the Dreamcast version today. I noticed a couple of things:
*- the DC version was slightly faster *
- the DC version with the vga adapter looks better than the Xbox that is connected with component cables
- it seemed like the Xbox version the characters sounds (intro, win and taunt) on default were barely audible
Can people tell me the differences they know of between all the home versions?
