Does Super Smash Bros. Melee Save Data to the Wii? No—GameCube Memory Card Only

No. Super Smash Bros. Melee is a GameCube game. It saves exclusively to a GameCube Memory Card inserted in Slot A or B—not to the Wii's internal NAND.

How to Save on Wii

• Insert a GameCube Memory Card into the Wii's top slots (flip the cover).
• Launch Melee via Disc Channel or backward compatibility.
• Game will prompt to create/save to the GC card.

Transferring Saves

• Wii → Wii: Copy GC saves via Data Management → Save Data → GameCube → Copy (requires two GC cards or SD card + homebrew).
• Wii → PC (Dolphin): Use GCMM homebrew to dump saves to SD, then import to Dolphin.
• Wii U: vWii mode supports GC cards + same process.

No Wii internal save support exists for any GameCube title.
