The concept of this is quite simple really.

Say, for example, the plugin is called "msWhatever.dll" then the your delphi DLL should be called "msWhatever_Delphi.dll" and the wrapper should be called "msWhatever.dll".

If theres's any naming problems, the wrapper will show a message on startup with the name of the DLL it's looking for..

Make sure both the DLLs are in the Milkshape directory.

See the Plugins Compiled forlders for examples of name pairing.
