The truth is far less dramatic, but I'd rather not drag on a topic that has clearly devolved into throwing rude accusations around.

Subcodes have no concept of data integrity, so you cannot do "proper and verifiable" dumps of them. Fireball is just blowing hot air - I've used their method, all they do is run multiple passes on the disc, and average the results together.
I'm not saying that it is completely impossible to do proper dump of subcodes, but you will not do it with unmodified commercial hardware.

Jhl did an analysis on the CDB rom and then compared it to the yabause wiki. According to him, only three commands were not documented there.
