Burning XBOX CD-R can be tricky, the following steps are proved to result in successfuly burnings:
1. Load XBOX ISO into Alcohol virtual drive (the drive may not display a disk insertion which normal, just ignore that)
2. Use CloneCD to copy the virtual drive (select Data, check to generate the Cue file)
3. Use FireBurner to burn the generated BIN/CUE files, the following settings are required:
Disc-at-once 96
Close CD
Autocorrect sub-channel
Autocorrect ECC/EDC
as shown below:
Don’t set the burning speed too high, I use 16x.
