I don't have this game; could you test whether the same FSW.dll
result can be done with a hex editor? That would be preferable to Notepad (especially since some in the reference topic had problems with the Notepad method).

I'm not sure how a hex editor will be easier or less problematic then Notepad. It's a simple copy/paste job with the section that need to be modified very easy to find.
The only issue I could think of is that Notepad loads the DLL file too slow.
