Crash

A Crash, Freeze, or Hardlock is what happens when Super Mario 64's code encounters an error, such as a division-by-zero, that causes the game to stop running and rendering frames. The audio may still play. This is in contrast to a softlock, where the game does still run but is stuck in an indefinite state or a loop where no controller input can change it.

Ways to crash the game

Exceed the object limit
Have too many objects at once on the screen
Send the camera into a PU
Bully Knockback dividing-by-zero
Failed Bully/Bob-omb angle double-to-short conversion
Deleting File B when it doesn't exist. (Go to "Copy" right when you get to the file select, then press "Score", press on File B, go to Erase, and click on yes.)
Moving a shadow above surface 12 while it's over OOB
