However, creating your own WAD file from a disc you legally own, for the purpose of system backup or modding, falls into a legal gray area (protected under "fair use" for archival in some jurisdictions, but actively contested by Nintendo's EULA).
Just remember the golden rules of the modding community:
In the pantheon of 3D platformers, few games shine as brightly as Super Mario Galaxy 2 . Released in 2010 for the Nintendo Wii, it refined the zero-gravity mechanics of its predecessor, introduced Yoshi into the cosmic chaos, and delivered some of the most inventive level design in gaming history. However, for a significant portion of the modding, emulation, and homebrew community, the game exists not just as a dusty disc or a digital download, but as a specific data container: the Super Mario Galaxy 2 Wad File .
Move the ISO to your PC. Use a tool like Wii Backup Fusion to extract the "Partition 1" (the game's data partition) into a folder. You are looking for the DATA folder, which contains filesys and main.dol .
