It works!

Nice shot :)

EDIT 1:

Just as a "pro tip":

The OEP is stored in EDX after these loops:


00401350 |> /AD /LODS DWORD PTR DS:[ESI]
00401351 |. |2BD0 |SUB EDX,EAX
00401353 |.^\E2 FB \LOOPD SHORT FastPack.00401350
00401355 |. 8B03 MOV EAX,DWORD PTR DS:[EBX]
00401357 |> 3B03 /CMP EAX,DWORD PTR DS:[EBX]
00401359 |.^74 FC \JE SHORT FastPack.00401357

Greets :)

EDIT 2:

D'oh! Didn't notice the tut from LCF! Well, thanks fot the tip :D

This way we have more solutions to one problem, which is great :D
