<r><QUOTE author="F1ReB4LL"><s>[quote=F1ReB4LL]</s>What do you mean by "used"? In db? Db only uses cue-bin images, ofc. SCM hash is needed when/if you decide to verify some descrambled image by scrambling it back. Messy discs may give a different result, depends on the case. Also, there are known ...

I'm not clear on the benefit of the .scm hash. What's the process for discs with a mess of descrambled and scrambled data? Is the .scm hash used, or is the .bin hash ...

If the descrambling isn't reversible for discs with mastering errors or unusual scrambling, won't it have to be redumped regardless of what the log shows?

If the .scm hash is the One True Hash, why not store it in the database?

Important to note that MPF is not DIC. DIC is what MPF uses but MPF has much more ...

I dumped a game that has audio tracks using Plextor+MPF and everything went fine. But how do I verify it with another drive? I recall using EAC or PerfectRip, but I could not figure out how.

<t>Do you have any other games besides Ace Combat 3 you can try to compare with the database? If so, try at least a couple of them to be sure your rips are coming out right. Try to rip them with IsoBuster + CloneCD's Game CD profile.<br/>
<br/>
I'd also be cautious ripping games with multiple tracks ...

Did you use IsoBuster for all of them? Do you have access to more than one optical drive that you could use to compare to? Can you post the info you got for Ace Combat 3, and what you did exactly to rip it or what guide you followed?

<r>I wrote a program to dump the Primary Volume Descriptor from a .bin file in IsoBuster format. Can be helpful to quickly dump the PVD to a file without needing to open IsoBuster, or used programmatically.<br/>
