In Star Tropics, at one point you have to get a certain piece of paper wet to reveal a "letter" to get the access code to be able to do something in the game. I'm not sure if the paper was in the instruction booklet or just in the box, but either way, never buy this game without everything. And if you have a rom of it, you HAVE to look it up somewhere. I just remember getting to that and being like... are you serious? Nothing in the game could tell you that passcode, so you'd basically be screwed.
