Using SDRip on my Dreamcast and cross-referencing TOSEC, I'm seeing that for some games like The House of the Dead 2 US NTSC, every file in the dump matches TOSEC's checksums EXCEPT the track02.raw.
Is this OK/normal, or is it an imperfect rip?
There are certain discs that have more than one print runs and different disc audio offset. I don't want to go too technical, but if your ringcode (serial at the bottom of the disc) is different from what is shown in the dat, then it's likely to be different.
Specifically for House of the Dead 2, the verified dumps came from *12S* 51002 and *13S* 51002 ringcodes.
If you have any other, it will likely not match. And what is more, we need these dumps submitted to us to match many unverifieds sitting around.
Again specifically for HOTD 2, we have *7S*, *9S* and MK-51002 1Mx ringcodes that are currently unverified. If you can help verifying any of those, I would be obliged.
