AI Dementia

AI Dementia is a somewhat normal phenomena that is an awful side effect of the personalization AI. As video game cartridges become older, they become more dusty - more damaged. This causes elements of the game to become corrupted - assets being gone, models becoming unstable, text becoming scrambled. The AI takes note of this, and finds that the cartridge is suddenly losing assets. It begins to remove more and more assets. Eventually, entire levels or enemies can be lost, and even part of the AI itself.

Replacement
When the AI deletes assets from the game, it usually replaces them with other assets. This can cause a bit of confusion, as some areas could look the same as others. This, combined with Dynamic Level Rearrangement, can make levels look completely different, such as Whomp's Fortress looking like the peak of a mountain, or Wet Dry World looking like a beach. It can also change enemies, having similar behavior to Enemy Discoloring.

The Downward Spiral
On very rare occasions, the AI Dementia can get worse, eventually causing the deletion of full levels. This phase it enters is called The Downward Spiral. In this phase, it may actually delete part of the engine, rendering the game unplayable. When the AI detects that the game isn't playable, it automatically assumes that it is a pirated copy, which causes it to display the Anti-Piracy Screen. If the game remains intact, however, multiple strange things occur. Not necessarily anomalous entities, but things like characters having corrupted animations, missing textures, and the game becoming incredibly buggy to the point that it is a challenge to play.

The AI Breaks Down
This is an incredibly rare phenomena, and has no known documentation. The AI has deleted most vital parts of the game, and is now beginning to delete itself. When it deletes itself, the Nintendo 64 system becomes incredibly hot, and the game begins running very slowly. It takes an estimated 24 hours to delete all of the AI. Considering the AI had deleted itself, the Mario 64 cartridge does not have the personalization AI, but it still has most of the assets lost.
