Time stop
Time Stop (also known as Timestop) is a glitch exclusive to the J 1.0 version of Super Mario 64, which allows Mario to move around when objects are frozen since a text box is supposed to have appeared.
Execution
There are a two ways to activate the Time Stop glitch, proximity textboxes and textboxes from holdable objects. Neither way works with all textboxes of either type.
Proximity Textboxes
"Proximity Textboxes" are defined as textboxes that appear when Mario is near an object. If Mario jumps right when the textbox is about to activate, then Mario will be able to move in midair until he touches ground again, after which the textbox will start. While Mario is in the air, time will be stopped.
Holdable Object Textbooks
By picking up an object that normally triggers a text box and then dropping it before it gets a chance to, time stop can be activated.
Effects
Other Versions of SM64
The developers patched this glitch in all versions of the game besides J 1.0. Time still stops for textboxes on other versions, but there is no known way to move around during this state.
