Doing this only to keep it in track.

@aldostools, about PS3 disc encryption, do you know if is it correct to say that odd sections are uncrypted and even are encrypted?

I checked the psdevwiki about it, but it's a little bit vague.

From the code implemented by NvrBst in line 225 of File.ccp of my fork, it looks like there is a set of regions defined in sectors 0 & 1. The even regions (starting from 0) are unencrypted and the odd regions are encrypted (i % 2 == 1). https://github.com/aldostools/webMAN-MOD/blob/master/_Projects_/ps3netsrv/src/File.cpp#L222-L228

Right, I forgot that the index starts at 0 when I write my comment 😝 .
