It's Blue Byte Software original(?) protection. Germany version(https://redump.info/disc/43270/) has SYSTEM.LSK. This file are protected.

1. Edit the 2nd line of ReadErrorProtect.txt
2. Try this process -> "Dumping Guide for LaserLock and Proring" of https://github.com/saramibreak/DiscImageCreator/wiki

Yes it has this hidden SYSTEM.LSK file (good to know), but DIC is not detecting it and then ignoring /sf switch. Maybe because it's marked hidden? I am trying with 5224TA, maybe tomorrow I try it with 716 but I think result is the same, I had this same issue with the Skidoo Racing.

:EDIT:

Yes tried with your exact example, no protection detected and /sf is ignored. Infinite hang on error sectors.

I tried and detected it.
Did you really do this?

I missed that but, I don't want to skip the file. Some of the sectors are good, error recovery needs to be better. I don't know why DIC hangs like that, when other programs do not. Perhaps you can improve this behavior to not need some special directives.

I've dumped it with your method, but readable sectors are missing and Reentrant's tool doesn't work for this. I'll do some capturing with bushound on alcohol so you can see what they do, claunia looked and they changed the mode so it doesn't hang.

In the mean time can you make it so ReadErrorProtect.txt can handle multiple files, Ski-Doo Team Racing is indeed using RingPROTECH but it has multiple files, here's a list.

style2.css
sno.ext
ds0.bl0
setup.mp
x-team_ss.ext
setextra.ex

OK testing.

Thanks, its is reading the sectors now but takes ages, I will let it run over night.

Another issue, I don't know if it's the DVD drives or a bug in DIC. There is no C2 errors but some sectors are corrupted after unscrambling. Here is the log of the latest one I had this happen. This only happens with my 716 and 760, it does not happen with any of the CD drives.

:edit:

Spoke too soon, still hangs about 10 sectors in, infinite hang. Must be the read mode or something.

- added: output 96bytes of SubChannel in subError.txt if crc16 doesn't match.

Some dumpers also have reported this. I've thought this is the problem of drives.

If you have time, please test below.
1. Dump your disc using cdtoimg.exe (d8 hacked) and descramble using Descramble_CDDA.exe.

If I remember right, cdtoimg uses the submode 00 (only main-channel is dumped). If Descramble_CDDA can descramble all sectors with no errors, I think the submode 08 (main+c2+sub) of DVD drive have bug.

Well I looked at the sectors in cdmage, on one disc the sync is shifted by 16 bytes to the right (safedisc) and on another disc the sync is shifted into the previous sector's ecc/edc area (normal disc). So yeah I think this is a bug with the DVD drives.
