Raven Shield 1.2 No Cd

[sabbey]

Quick question from someone somewhat new to NO-CD patches...

I just ordered the Raven Shield game and downloaded the 1.2 patch for it. However, I am trying to pick which NO-CD patch should go with it. I see there are at least two listed for it here.

First off, which would you recommend and two, what is the file - CORE.DLL used for?

Thanks all...
