Some games don't freeze with AAAAAA, but they will occasionally have really odd side effects. Try using it with Castlevania 2. You'll have to leave town, before you notice anything different.
Also I remember the no battle code for Final Fantasy. It was OOTPVP. I used to get past the stairs leading to Lich's chamber using a save state. ( and reloading it with no code active. Though you can't do this on a real nes) Some of the stairs in the final dungeon also have this problem.
A funny side effect with that code is each time you get into a fight, and go back, if you look at the stat screen, you'll notice it makes the characters level go up by one. (Though it has no effect on their stats.) If you keep getting into battles, you'll eventually surpass level 50, and after 99 it'll start using letters with numbers. (A1)
In the game monsters run away from you depending on your level. When your level becomes B1, the monsters think you're so powerful that every single one of them in the entire game will run away from you. Even the bosses. Seeing Chaos run away, and then disintigrate is pretty amusing.
