The compilation probably says it all and it contains Street Fighter 1, 2, Alpha series and 3 series. Even Ultra Street Fighter IV will be included as a pre-order digital bonus included with the compilation although Playstation 4 already has that version all along and especially that Ultra Street Fighter IV is playable on Xbox One through backwards compatibilty. All versions in the compilation are probably based on the arcade versions although some of the games don't have the Training Mode for some strange reason. Some have the Online Mode but the others don't.
For Street Fighter III series, the second one, Second Impact, happens to have the true widescreen mode which can be enabled through the arcade operators menu although it is the only CPS-3 game to have that and the arcade system is 32-Bit-styled so having widescreen in 32-Bit arcade games is kind of rare. There's also the widescreen support for certain Playstation 2, Gamecube and Xbox games. Music for Street Fighter III series is obviously from the arcade version so if you're playing Street Fighter III Third Strike on consoles prior to the existence of this compilation, chances are that you hear the arranged soundtrack and especially for better quality sound effects and voices. The arcade version of Street Fighter III Third Strike is kind of too much or something to handle hence the lag or some sort it may seem to be due to the limitations of the RAM or something.
One cool thing that catches me the attention is that on the Game Selection screen, you get to see the arcade system the game is running on originally. To include Ultra Street Fighter IV in this compilation as a pre-order digital bonus is one challenge Capcom had faced. Obviously, it is a separate game and not part of the compilation. If it is, they will need additional rights from Taito to have the arcade systems the game's running on in the list but I figure out that it's unnecessary. This pre-order digital bonus applies to Playstation 4, Xbox One and Steam versions of the compilation which Playstation 4 and Steam owners will have those versions of Ultra Street Fighter IV with Xbox One owners receiving both Super Street Fighter IV Arcade Edition and Ultra Street Fighter IV through backwards compatibilty. Needless to say, as a pre-order stuff, it is obvious that it had to be done before the game's release date.
On the Switch, the compilation comes with Super Street Fighter II The Tournament Battle which is in the arcades only where machines can be linked locally for tournament purposes.
Needless to say, I'm not a goodie at this game genre but then, I already had bought some other fighting games for the Playstation Vita.
