Super Mario 64 1.5 Ztar Attack! is a Super Mario 64 ROM hack made by TheGael95 and released on July 31, 2017.
Containing 170 stars, it is one of the largest ROM hacks in terms of star count and the creator’s biggest completed project. The hack contains all-new levels, custom graphics, objects, enemies, and music. The player begins in a grim-looking version of Peach’s Castle. Most level entrances are still present, but they are explored in a different order and do not always go to equivalent areas in the original game.
The game’s levels are also interconnected, with many levels containing entrances to other levels in addition to their regular entrance found in Peach’s Castle.
