Unlockables Guide

[Link]

Does this exist somewhere? For how to actually unlock stuff without cheats? How about some of the faces? Are they Coupon Code only or are there in-game ways to unlock them? I know I unlocked the two faces by completing the "Eating Game" in the Arcade, so I was wondering if this also exists for the others that get unlocked with Coupons?

Basically, I want to unlock everything the "legit" way as opposed to using codes/coupons.
