Hello Guys, i have a problem to dump this one.

It uses what seems to be a weak sector, and DTC crash right away when it reads it, it says bad sector, then the drive head is going nuts and DTC exits.

i have done an extended DSK of the game, if you can look at it below :

Dump the disk to just stream files without any guide format, then I can take a look, e.g. without say -i4 parameter.

i asked to a guy that has good knowledge of amstrad cpc loader routines.

The game performs a check for sector 48 on track 0 which should be 100 bytes in length. Samdisk have not been able to image it correctly....

Now i need to try to dump it with kryoflux..... let's see how it behaves with your command :)

It just doesn't work :( Because the CPC disks are PER side, and the dtc -fimagename -i0 -i2 image the disk like if it was a double sided disk......

Do you have any clues ? Because i must send back to the owner the disk :(

Doesn't matter. The drive ignores side 1 and dumps side 0 again. So just dump it once called side 1, flip disk and dump with file name called side 2. Upload all files.

Simply remove the -i4 parameters and whatever that belongs to them to prevent verifying of the disk format.
If you post the command line used, I can suggest a new one for blind dumping.

Also you can constrain dumping to side 0:
Dtc -fimagename -i0 -g0 -i2

You probably need to stop the dumping at track 41 for many 3'' drives:
Dtc -fimagename -i0 -g0 -i2 -e41
