SFII was released a little buggy. When my son and I played, the controllers randomly swapped places... then disabled one. I had to completely restart both controllers and the game to get it working correctly.

Considering how long they took releasing it... this is completely ridiculous. Hopefully this fix makes it a bit more stable. Well, at least no cheats have materialized like the card game (if you can call it a card game... it's no Mille Bourne's or Magic) they recently released.
