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.
