Can I modify game code by accessing the DLL files?

Question

Can I change the source code of a windows DLL file? Can I change the source code of another application?

Community Answer

Yes, but making changes is risky because because these are compiled files. If you want to change code, first backup your original files, then you can use the "Resource Editor" to edit and save the DLL.

Community Answer

This method is only applicable to .NET-coded DLL; if it's coded in C++ or Delphi, it most likely won't work.

Question

How do I decompile a C+ dll file?

Community Answer

Most likely you can't––you will need advanced debugger to roughly read the machine code. You will need the pdb, which most likely isn't shipped together.

Question

Do I need to save a DLL file in order for the program to work correctly? If so, how do I do that?

Community Answer

Just make a copy of that file. DLL files are necessary, do not delete it, or else a lot of stuff will break.
