You do not need to unpack it.
Use StrongOD and if your on windows seven Stealth 64.
And prehaps HideOD.
You have to setup your settings right.
I have an OllyDBG in my sig that I think still works.
The games packed with Themidia but if you use olly setup right you can bypass all that and it will be unpacked in memory.
You probably won't be able to dump it and fix it without mad skills but you can still do what you need to do
