I do not know. I think that Nero sucks, but Toki was using Nero and I wanted to answer him. My brother usually makes his backups with Nero and he had little problems with the protecton scheme (except with games heavily protected as Breath Of Fire IV, Saga Frontier 2 and so on). About other software: I noticed that CloneCD images (.img extension) files are compatible with CDRWin images. I mean, if you burn a CUE/IMG set with CDRwin it works. So I assume that the .IMG part coincides byte-by-byte with the .BIN file created by CDRWin and that (maybe) the protection scheme information is contained in the subchannel data (.sub) file cerated by CloneCD. Do you think this could be a correct guess?
