The test version test_20190508_190259 (currently the latest test version on the first post last I checked) has a bug when dealing with SafeDisc protected games. When using /sf it will appear to detect the SafeDisc protection but at the end of the dump with try and reread the bad sectors as if they were not supposed to be there as part of the copy protection.
I believe my report was not clear, there were no C2 errors for me. Only EDC/ECC errors from weak decoding and only at the end of the disc with lba > 200000.
I will redump and add logs later.
