Does the Wii Keyboard Work with Games?

No. The official Wii Keyboard (released 2008, Japan-only; later elsewhere) only functions in:

• Wii Menu (channel naming, search)
• Internet Channel (URL entry)
• Wii Message Board
• Some WiiWare titles (e.g., Animal Crossing: City Folk chat)

Why Not in Games?

• Games are programmed for Wii Remote/Nunchuk/Classic Controller input APIs.
• Keyboard lacks analog sticks, motion, IR pointer, and many game-specific buttons.
• No SDK support for keyboard mapping in retail game discs.

Workarounds (Homebrew Only)

• Emulators (NES, SNES, Genesis) on Homebrew Channel can map keys.
• USB keyboard support in Linux on Wii (obsolete).

For typing-heavy games (MMOs, strategy), the Wii is not the platform.
