Have I stumbled across something groundbreaking or is this just the fabric of my imagination?
Like other users on the forums I have been able to backup (DVD’s aside), all versions of secuROM until my MotoGP3 derailed my plex premium. However twinpeak method has been hit and miss with MotoGP3 with my first backups getting to the actual race screen before being identified as a copy. More recently I have been able to make a backup (twinpeak’d using a-ray scanner and alcohol) that has passed authentication even in the race screen. Why would this copy work when others hadn’t?
I loaded a MDS and a BWA of the MotoGP3 disc into BWA Builder 5 and found that alcohol and blindwrite obviously read topology differently as the picture will show. The red line is the MDS file from alcohol and the green line is the BWA from blindwrite. Please note that this actual picture is the topology from Rollercoaster Tycoon 2 (SecuROM) not MotoGP3 but the differences were there on MotoGP3 disc. So my question is which program is “right” and if one particular program is “wrong” maybe this is why backups made with “wrong” program dont work.
ps. I also noticed that alcohol had one read error at the end of the disc that blindwrite did not detect, I wonder whether this error is another reason why some backups don’t authenticate.
Anyone with some technical knowhow that can set it straight for the record would be good. : )
