I don't have a problem with remembering games. My problem is that I remember cheat codes and I have no idea what they belong to. I'll be minding my own business when I suddenly remember:
CTMV-W26K-R5KN-SIBK (that's the password and I swear it works for whichever game it's for), or Z,A,R,Z,A,B. Lately, I've been thinking L,Y,X,R,B,A (I just remembered, the last one isn't a cheat code at all. It's the way I configure my buttons in Street Fighter II for the Super Nes!).
