I've heard some that are just absolutely impossible.
1. Beat All Star on Hard or Very Hard with out getting a game over once with Marth or Roy, and you will unlock the Fire Emblem Stage.
That's one that I can think of for now. Anyone else get any ideas, copy this one, and paste it, and add it like you would a list. ((To make it less messy looking.
Powahawk, I like more playing a mid speed character, like Link. I'm not too good speed characters either.lol But I wanna try Sonic out.
