Absolutely incorrect. Alpha Anthology has a special "dipswitches" menu for adjusting gameplay elements based on multiple revisions of the Alpha series arcade code.
Edit: I should probably clarify something. While 99.99% of the adjustments were bugfixes, a change to even a single active move typically had rippling effects across the entire game that could be on-par to a whole balance pass-- none of this is currently documented, and I believe that there's actually quite a bit of history here should someone want to dig in deeply enough.
