Module Name:

|
|
SierraCartRacing.cpp
|
|
|
|
Abstract:
|
|
|
|
A hack for Cart Racing (Sierra). They call InitializeSecurityDescriptor
|
|
which trashes an old stack pointer which is later needed. They call
|
|
CreateSemaphore with an invalid security descriptor:
|
|
|
|
lpSemaphoreAttributes->lpSecurityDescriptor == 1
|
|
|
|
This looks like a semaphore they use to prevent getting executed twice,
|
|
Note, although it doesn't matter if the Semaphore doesn't get created,
|
|
I thought it better if this worked.
|
|
|
|
Fix:
|
|
|
|
CreateSemaphore: set the security attributes to NULL (default)
|
|
InitializeSecurityDescriptor: do nothing, since it's not needed anymore
|
|
|
|
Notes:
|
|
|
|
This is an app specific shim.
