[Ez question] How to require a DLL?

Hey ASM Coders/ Gunz modders

I have a dll i need to load into gunz so it starts when gunz starts. Only i dont know how to do this with OllydDBG or Hex Editor.

Also: How do i get gunz to REQUIRE it, so it won't start without it?

Help please!

Thanks in advance

Solution: LoadLibrary.

clue fmod.dll

Wouldn't recommend calling LoadLibrary like that.

You can do it the pe edit with any file loaded into gunz or gunz itself... fmod is just the one everyone seems to use...

Files the can be used:
Gunz.exe (theduel.exe)
dbghelp.dll
fmod.dll
gdiplus.dll
