[Wine] dll override basic question

[jprosser]

Hi Folks,
I'm new to Wine and have some basic questions that I couldn't find answer to in the FAQ or forums.

Some posts talk about dropping in native dlls into the .wine/.../system32 directory to get apps working, while some posts (and the FAQ) talk about using the wine configuration tool.

In order to properly override a DLL, do I install a copy from an MS-windows installation AND specify it in the wine configuration tool?  

What do I do if the dll isn't listed in the wine configuration tool drop down?


Is this what winetricks does?  

Thanks!
