Batter Up (accessory)
From Sega Retro
The Batter Up controller is a special Sega Mega Drive peripheral designed with baseball games in mind. It was only released in North America and Brazil.
The Batter Up controller is shaped as a 24-inch bat surrounded by blue rubber foam. It responds to the user's movements, similar to the much later Wii remote. There are a number of buttons on the side of the controller meaning it can also function as a normal control pad. The controller is extremely rare and so little has been documented about it.
A similar peripheral was also released for the Super Nintendo.
The Batter Up controller is said to be compatible with "almost all" Mega Drive baseball games. This has yet to be confirmed, however the controller is known to work with World Series Baseball. The following is a list of Mega Drive baseball games that may be compatible:
It is assumed the unlicensed Shi Jie Zhi Bang Zheng Ba Zhan: World Pro Baseball 94 won't be compatible.
