Loader or inline-patching for Safecast.

[SystemeD]

Hi all,
I've read some threads and tuts about loaders and inline patching and I tried to apply them on a target protected by Safecast (Safedisc) 2.20.020, but it seems this target is a bit different from the other ones.
What I need is to patch a dll extracted by the packer, written on the temp dir and loaded with LoadLibrary.
My problems are:
1 - (At the moment) I think I can't use a loader because when I try to start the app with CreateProcess, the registration form appear but after the real app doesn't start. It seems the protector acts like a debugger of itself so it doesn't work if this process has already a parent process which started it. Does exist another way to do that?
2 - If I try to inline patch it, I have no rights to write on the loaded dll space and moreover I don't know where the dll will be loaded so I don't have the right address to patch. I must use VirtualProtect?
3 - Does other packers work this same way?
Thanks
