 Module Name:

   NHL2001.cpp

 Abstract:

    EA Sports' NHL 2001 has a bug where if the platform returned by
    GetVersionExA is not windows, they don't call the GetDiskFreeSpace and
    then report no free space to create a tournament season or playoff.
    Unfortunately, a generic version lie does not work because the game is
    safedisk protected, so we both apps to have the same GetVesionExA.
