"This game has [duplicate] data from another game", maybe.

I'd say your first example (South Park episode) wouldn't count, because the developer probably intended to include that. Second example, containing content from another (unrelated?) game, would.

Basically:

- Data has to be from a game
- There has to be no good reason for it to be there (i.e. if game A used a few sprites out of an entire included bank of Game B's graphics, it wouldn't count - that'd just be standard unused stuff, maybe?)
- Earlier versions of things would count, and should probably be mentioned on the original game's page too

Basic category guidelines, for now. Others can adjust as needed.


One thing that makes me "hmm" is stuff like SMB3, which apparently contains duplicate unused copies of a few PRG banks in the unused space of other PRG banks.

I'm trying to make a distinction in the sense of "data probably left from a previous ROM burn thanks to the wonders of chip reuse and free space" and "stuff the compiler jammed in from memory" (like file listings or documents), if that helps anyone catch the distinction I'm trying to make.
