One time my Zelda II cart glitched out and the veil was pierced: I could see the life and magic meter sprites including their movement when either gauge was depleted. This reminds me of something else. When I was a kid I wanted to create my own Mario game. One of the ideas I had was to have an optional, additional sprite I called "The Chunk" that would be used for auxiliary character animation; for example to make Princess Peach's hair flutter when she jumped or ran. Well, my supposedly kid-genius self wasn't so original after all; in Super Mario Bros. 2 (the Doki Doki Panic derived one), the playable characters do indeed have a Chunk: a small white rectangle that moves around with them, layered behind the character sprite, and provides the sclerae of their eyes. I'm actually still working on that "Mario" game. It has Mario-like platforming physics but completely different premise and auxiliary mechanics. Something like the Chunk is used to switch the game's terminal screens from red (normal state) to green (hacked state).
