NFL 2K2 (U) [MK-51168]

Post by majorpbx » Sun Jul 09, 2017 3:48 pm

Here is an odd one, I've noticed that usually all the audio tracks are different in a variant but this one only has Track 2 as the variant. If someone can confirm this disk in my collection I would appreciate it. Also, I'd like to mention that the disk is in excellent condition and there is no foil damage just in case anyone is wondering.

What I can tell you is that checksums of track02 appear legit, they can be obtained by changing the offset of the already verified track with *2S* ringcode.
There are other cases where the low and high density areas have been mastered with a different offset and this might be one of them, although this is the first spotted case where the low density has different offset than another disc and the high density has exactly the same.

I own yet another variant of this disc with ringcode *4S* 51168. In my disc, both tracks have different offset as expected.
I suppose we need to wait until someone else dumps the *5S* disc and gets the same checksums. However, arriving at the "correct" checksum for track04 by accident would be too far fetched IMO, so I am well inclined to believe this is absolutely legit.
