Where Does MySims Kingdom (Wii) Save? Save Location Explained

Assuming you mean MySims Kingdom (Wii, 2008) — the "Sims Kingdom" title doesn't exist.

Save Location: Wii Internal NAND Flash Memory (512 MB) — specifically /title/00010000/534d4e45/data/ (Title ID: SMNE).

• NOT on the Game Disc. Discs are read-only.
• NOT on SD Card by default. SD Card stores: Photos (Wii Message Board), Wii Channels, Virtual Console/WiiWare games, not standard game saves (unless developer specifically implements SD save, which MySims Kingdom does not).
• Copy to SD? Wii System Menu → Data Management → Save Data → Wii → MySims Kingdom → Copy → SD Card. This creates a backup. Game still loads from NAND. You cannot run the save directly from SD.

If you meant The Sims 2: Castaway (Wii)

Same: Internal NAND only. No SD save support.

If you meant The Sims 3 (Wii – cancelled) / MySims series

All Wii saves → Internal NAND. SD is for backup transfer only.
