Ingame Achievement System

The Ingame Achievement System, more commonly referred to simply as "Achievements," is an achievement system for Super Mario 64 implemented by the Personalisation A.I. It usually appears in the top right of the screen.

Menu
Usually, a menu for achievements is associated with the achievement system, most commonly opened by L+R. Its appearance differs greatly, though many have described the menu as "rudimentary."

On some rare occasions, the menu spawns you into an isolated area, with the achievements the player has collected present on small pillars throughout the room. The appearance of this room also differs greatly, with the only consistent attribute being the pillars. Some have even described the achievement room as its own area accessible within Princess Peach's Castle.

Theorizing
It is believed that its removal was due to large sum of money prize if all achievements are completed.
