Talk:Super Street Fighter II Turbo HD Remix
It reads "Some O.Characters are a combination of their CE/HF/SSFII versions." at the main page, at the moment. I am not aware of any CE or HF influence on the SSF2 versions of the characters in ST. They are basically the same, but working under the ST engine, which makes them all recover marginally faster from attacks (as all updated ST characters do) and get a few more cancellable attacks, probably due to some extended kara-cancel period that I suppose ST has. That aside, and excluding version specific bugs such as Gief's reversal suplex, ST old characters are SSF2 characters.
