I used a Shenron wish on the items stuff, expecting the game to open up all six slots. Instead I'm at 4, although I can stack two on each tile. That's nice, but how do I unlock the other two slots?
EDIT: Fffffffffffffffffffffffuck yeah I finally got Piccolo. My 12th hard run, along with a z-hard and two normals.
My first drop from one of these. I did probably 35 hard runs for King Vegeta and got nothing. Between Cyborg Tao, Jackie Chun, Bardock/Frieza/Chilled, I did probably 40 hard runs total. Never got a single drop.
Floodgates are open.
