Oh great thanks you to take a look at this !
@F1ReB4LL: You're right, I use the same command each time, I only change the name wit a .bat file. I copy the command from the guide and as I dump psx games too, sometimes the /nl is here, I compare and it does nothing on mega cd games.
For the ring code sure, I was more busy understanding how to make a good dump

@sarami: What I can say physically, we can clearly see the first track in the center of the CD and then a blank part where the rushes are. Then we can see a burned part on the outer of this blank section.
Can we asssume that the brushes area could be blanked ?
For the noc2 flag non zero area, there was a drive correction, some jitter stuff that try to interpolate the data. In this case, as the drive speed is faster, he may found something on brush but can't read, maybe he is trying to interpolate in own error.
Btw do you think that if I remove the brushes, there would be little holes, something will change or the holes would make the same ? (I assusme that hole = read error too)
Thank you again for your help, and hope we ca fill this area with 0
