You can now map keyboard to player 2, if you so wish! You can have keyboard on both p1 and p2. This should help for people that can't get controllers to work and need to use joy2key.
Mapping controls is in the "controller" menu, and mapping controllers to p1/p2 is now separately in the "controller set" menu.
There are now controller shortcuts for A+B and B+Y. A+B activates the throw storage bug (no attacks come out as you hold it, and throwing occurs when you enter throw range), and is now much easier to do thanks to the controller shortcut. B+Y is the input for a new feature: the Kyanta Cancel! AKA Kyan-Kyan/Can-Can or KC. Think of it as a roman cancel that takes an entire bar of super to do. It will also increase the damage of the next attack you do, even if that attack doesn't combo. The damage buff does not stack with taunt buffs. See what kinds of dumb things you can do with it!
