Listing the different protection schemes for the 8 subcoding channels...
Channel P: no protection, Channel Q: 16-bit CRC, Channels R to W:
[FONT=Arial][SIZE=2][SIZE=2][FONT=Arial][SIZE=2][FONT=Arial]To protect the data in the subcoding channels R to W, a (24, 20) Reed-Solomon error correction code is used. To improve the burst error correction capability, 8 times interleaving is added to this error-correction system. The first two symbols in a PACK have additional protection with a (4, 2) Reed-Solomon error correction code.

Only this disc? or all disc you have? I tried the same option with MegaRace of 3DO but Main channel was shifted correctly with offset.iR0b0t wrote:Main channel is shifted by 30 samples forwards
I'm not the original dumper, I only saw the logs. In idlord's case /s 2 didn't help. In one of the logs you output a table describing TOC with pregap and this table is computed using RMSF in SubQ, yes? The problem with the CD is that RMSF in Q channel is bad but not random. For example at some point (say LBA 90000), RMSF is changed to some low value like 00:24:24 and goes up on each frame. After some sectors it restarts again and goes up.sarami wrote:This? /viewtopic.php?p=24193#p24193reentrant wrote:subchannels are corrupted.
