ok here we go

with CDrwin you need to create a image file (bin file) to your hard drive and then burn back to the blank CD, if the game needs a patch applying to the image you need PPF-o-Matic to insert the patch into the bin file you have created.
then you just simple burn back to your blank CD.

With clonecd you simple doe the same but you don't need the patch as clonecd if 100% compatible with your writing drive will do an exact copy of the disk.

if you goto www.megagames.com you will find tutorials.

hope i have helped.
