I downloaded the Yankee Stadium(CAS), Marlin Field(CAS) and Target Field(CAS) all of them says: Simply copy the the venuday & venunite .BIG files into your mvpbaseball2005/data/stadium folder, but, if i do that each one replaces each one, i mean, the Yankee replaces Marlin an this one replaces Target.
Please, could you to explain it better.
