copied cds wont work, please help!

RA2, Alice, Undying (I think), and some others have safeDisc2 protection. Lots of drives will read to an image file ok, but not many will correctly burn the image to a blank cd. Often you can use a fixed game.exe, but in the case of RA2, the setup.exe is also protected by SD2 (ouch!) therefore it won't install.

You need to find out if your reader/burner is compatible with cloneCD (it writes in dao/raw.) A few plextors and some phillips and HP's will do the job. Sometimes though, you don't really know what the drive actually is because manufacturers use one anothers hardware.
