Here's why:
* Compatibility: The Wii steering wheel is designed to work with specific Wii games that have built-in support for it. It uses Bluetooth technology to communicate with the console, and older games don't have this functionality.
* No Emulation: The Wii console itself doesn't have the ability to emulate older game systems, so it wouldn't be able to "translate" the steering wheel inputs for older games.
In summary: If the game you're playing doesn't specifically list the Wii steering wheel as a supported controller, then it won't work. You'll need to stick to the standard Wii Remote or other compatible controllers.
