Ok, just got me Street Fighter Alpha 2 and 3 also for Capcom Arcade Stadium 2nd (46% off atm – only a bit over an € per game).
I already own them via the 30th Anniversay Collection, but I discovered some added functionality in the Arcade Stadium “package(s)”. Not only are leaderboards free (no need for NSO), but there’s also a rewind funtion you can assign to any button.
But best of all (I don’t really use the rewind function myself) you can assign a button to perform the light, medium and heavy punches at the same time and another button for the kicks (I use respectively ZL and ZR)
At first I didn’t know what this was for (it’s a feature in the PS1 version of Street Fighter Alpha 2 too btw) as pushing either of the buttons assigned just did (iirc) a light punch or light kick (it didn’t do all three of them at the same time of course).
But then I realized that some of the Special Moves, EX Move, Super Combos, Custom Combos (or what they’re called) are triggered by pressing 2 (or sometimes more) of the punch and kick buttons at the same time (when your meter is full/ready that is).
So this way you have an option to do a “shortcut” by pressing either one of these “special” buttons or both simultaneously (depending on the game you’re playing; the state the meter is in etc. of course)
What Arcade Stadium 2nd (and probably also the first Arcade Stadium) also does a lot better than for example the 30th Anniversary Collection, is explaining how the games actually work. It comes with a very detailed and comprehensive manual for each and every game available.
It’s such a wonderful package(s) imo, and I really hope Capcom will continue their good work and make 3rd and 4th Stadiums with the rest of their arcade games library.
