Super Mario Galaxy Becomes the First Fully Decompiled Nintendo Wii Game

Super Mario Galaxy has become the first Nintendo Wii game to be entirely decompiled, a major reverse-engineering milestone that paves the way for native, unofficial ports to modern hardware. The breakthrough was achieved this week by the developer group SMGCommunity, transitioning the complex process of console decompilation from the GameCube era into the Wii generation.

Following the successful reverse-engineering of the source code, developer collective Luma’s Workshop immediately announced “AstroCore,” an upcoming unofficial native PC port of the 2007 platformer. The development team has explicitly stated that AstroCore will be “100% coded by humans.” This declaration separates the project from a recent wave of “vibecoded” fan ports heavily reliant on generative AI—a practice that often introduces severe technical debt and compromises the long-term stability of the software.

While the team has not formally announced a smartphone version, historical precedent points toward an eventual mobile release. Earlier this month, the complete decompilation of the GameCube fighting game Super Smash Bros. Melee was swiftly followed by a functional, community-driven Android port.

The decompilation of Super Mario Galaxy marks the beginning of a broader movement for Wii preservation. Several other high-profile Wii titles are currently undergoing similar reverse-engineering efforts, including:

• Super Mario Galaxy 2

• The Legend of Zelda: Skyward Sword

• Xenoblade Chronicles

• Mario Strikers: Charged

• Rock Band 3
