PSX: First LibCrypt CDROM Discovered!

[superg]

Ok, couple more findings:
Indeed, Gekido has a backup libcrypt key in audio subchannel, https://redump.info/disc/833/ updated.
Net Yaroze disc doesn't have mirror or backup keys, just 6 bits in 6 first libcrypt sectors, https://redump.info/disc/45854/ updated, .SBI or .LSD can be downloaded from there.

I've also updated my redumper libcrypt detection code so it should be a little bit better although theoretically there might be false positives. nocash - thanks for all the hints!

Lastly I have yet to find my PAL PSX to check if the disc boots, chances are low but I'll try to finalize it this week.

PAL PlayStation boots the disc just fine (and it's playable).

JP PlayStation doesn't boot the disc.
