Super Mario 64 × 2

Super Mario 64 × 2 is a half-sequel, half–director's cut of the critically-acclaimed Super Mario 64 that attempts to fix latent issues with the game while also providing new content. The game was released for Nintendo 64 in early 1998, using the system's full capabilities in contrast from its 32-bit predecessor.

Plot
One night in the Mushroom Kingdom, a strange green meteorite lands near Princess Peach's Castle.

The next morning, Mario arrives to investigate, only to find that the object has completely vanished, leaving only a small crater behind.

Mario enters the castle to learn that Bowser has broken the meteorite into Green Stars and used their power to take over. Princess Peach and her Mushroom Retainers are held hostage in their own castle by guards patrolling the halls.

It's up to Mario to use the old painting rooms to find the scattered Green Stars and save the day.
