hacnho described a very good way in his tutorials about IAT-Elimination to find the magic jump. This method also works very well here. I've unpacked the dll now, but my problem are the relocations...

Also make sure you don't use normal breakpoints on the APIs because Arma detects them and will then crash the program.

Then set a bp on the .text-section. Next time you break you should have reached the OEP. Dump with LordPE and fix Imports.
