To play as War Mech & Ichiro:

In the two-player mode, players will fight in
the home stage of the character chosen last -- that
is, unless a code is entered. To enter a stage 
select code, move to each character listed and tap
START after each one, then go to your desired 
character and select as usual. All of these codes 
are for the two-player mode, except the Random AI 
trick.
