We now have 4 programmable buttons, add to that the 4 already accessible buttons, and the directional pad.
so, heres an idea.
L and R could be set for the swords. L could be the first player's sword and R could be the second player's sword.
A and B could be for items, with A being player 1's item and B being player 2's item.
Start brings up the subscreen, and you can select A and B button items.
the 4 extra buttons could be for moving player 2 while the 4 arrow keys, player 1.
Obviously its not as simple as that, but I thought it'd be nice to bring it up, in case someone is stupid enough to try it
