I made a working copy of Star Wars: Empire at War (CD version) using
CloneCd 5.2.8.1, BWA builder (from BlindWrite Version 4), Twin Peaks 0.2 and a Nec DVD RW ND 6650A as the reader and writer.
First create an image using CloneCd. Nothing special here, just make an image. Then use BWA builder to make a BWA file. I used a read speed of 8X, and max sector of 50,000. Save the .BWA in the same folder as the image. Then run Twin Peaks and point it to the correct image and BWA file. I set the stepping to the default of 15. Once it's finished (it says "Done") burn the "patched.ccd" file to a CD using CloneCd. I used the "SecureRom New" profile and burned at 8X. When it's finished (about ten minutes) it's very important to deactivate the CloneCD tray,
AnyDVD tray, and any other virtual drives or emulation software you have. Reboot.
Using the above method, my backup worked the first try and every try since.
