Wiimmfi is a service that mimics the original Nintendo Wi-Fi Connection. It was created by developers Wiimm and Leseratte just days before the official shutdown in 2014. Since then, it has grown to support almost every Wii game with a wireless mode, most notably Mario Kart Wii, which often has hundreds of players online at any given time.
There are several ways to use Wiimmfi, depending on your setup:
On Wii U, you’ll be using vWii—the built-in Wii backwards compatibility mode. The process is nearly identical:
Note: Your Wii U GamePad won’t work in vWii mode—you’ll need a Wii Remote or Classic Controller.
Wiimmfi takes anti-cheat very seriously, especially in Mario Kart. Using hacks in public rooms will result in a permanent ban. If you are a first-time user, you may face a 7-day activation wait when trying to join Mario Kart races—this is a security measure to prevent ban evasion.
