Sega has released some peripherals in bundles with their Wii games, so-far with older games ported to the Wii system.

Squad Gun
Ghost Squad was released in Europe bundled with a Wii Zapper-like peripheral called the Squad Gun. This bundle is referred to as the Ghost Squad Action Pack. There is a similar pack combining House of the Dead 2 & 3 with the gun. Judging from images on the Internet this bundle is also available in Japan, but features the official Wii Zapper gun instead of the Squad Gun. A "super" package also exists. It is called the Super Squad Gun Pack. This is an all-in-one bundle of Ghost Squad and House of the Dead 2 & 3 with the Squad Gun.
Catch'n Fish
The Sega Fish'n Pack bundle features the Sega Bass Fishing game, as well as a fishing rod called Catch'n Fish. The fishing rod looks similar to that of Logic3, but they are not the same.
Wii Maracas
The Samba de Amigo game included Maraca sticks that the Wii remote can be plugged into. It came one Maraca for the Wii remote and other for the Nunchuck controller.
