SafeDisc 1 games crash about safediscshim HOT 4 OPEN

Figured out the root cause, it looks like the new injection mechanism involving overwriting the entry point from 8fedebb does not work for SafeDisc 1 ICDs. Simply calling Initialize from DllMain for ICD like in older revisions makes the game work.

While initializing from DllMain is unsafe due to loader lock, as far as I can tell, there's literally no other way to do this for ICD specifically. dplayerx.dll seems to be loaded before ICD entry point (from import table?) and it needs Secdrv driver in its own DllMain meaning that the shim must be initialized by this point or dplayerx.dll will crash.

My memory aches trying to remember what rule of thumb I must have read in the past, but you might want to take a notice at:

I have a solution in mind for this; I will work on it once I have completed some other obligations.
