Transferring Data from Nintendo 3DS to Wii: Not Possible

You cannot transfer data directly from Nintendo 3DS to Wii. They are separate generations with incompatible architectures, storage formats, and no built-in transfer pathway.

Why Direct Transfer Doesn't Exist

Different hardware: 3DS (ARM11, PICA200, 128 MB FCRAM) vs. Wii (PowerPC Broadway, ATI Hollywood, 88 MB MEM1/MEM2).
Different OS: 3DS runs proprietary Nintendo OS; Wii runs IOS/BC/MIOS. No shared APIs.
Different save formats: 3DS saves = encrypted FAT16/32 on SD (NAND for system). Wii saves = proprietary format on NAND / SD.
No connectivity: No cable, wireless protocol, or cloud service links them. Wii Shop / DSi Shop / 3DS eShop were separate.

What You Can Transfer

Source → Destination	Possible?	Method
3DS → 3DS (or 2DS, New 3DS)	✅ Yes	System Transfer (Settings → Other Settings → System Transfer). Transfers: NNID, eShop licenses, saves, friend list, activity log, SD content.
3DS → PC (Backup)	✅ Yes	SD card reader → copy `Nintendo 3DS` folder. Or Checkpoint (homebrew) for individual save export.
Wii → Wii (or Wii U)	✅ Yes	Wii: SD card → Data Management → Save Data → Copy. Wii U: Wii System Transfer Tool (moves everything to Wii U mode).
Wii → PC (Backup)	✅ Yes	Homebrew (Homebrew Channel + SaveGame Manager GX) → extract saves to SD → PC.
3DS → Wii / Wii → 3DS	❌ No	No pathway. Save formats, crypto, architectures incompatible.

Game-Specific Cross-Play (Not Save Transfer)

Pokémon: 3DS (Bank/HOME) → Switch. No Wii link.
Monster Hunter 3 Ultimate: 3DS ↔ Wii U (local wireless) for multiplayer — not save transfer.
Super Smash Bros.: 3DS → Wii U (character customization transfer only).

Summary: Back up 3DS saves to PC via SD. Back up Wii saves via homebrew. No cross-conversion. Play each game on its native platform.
