Defective/Error Dreamcast Launch Games?

[SomeOtherFaker]

Forgive me for this being my first message here, and for it possibly being in the wrong part of the website, but I've been losing my mind over this all day.
I've been trying to find a copy of Sonic Adventure to play, but apparently unplayable copies of the game exist, that much I know.
My problem is how do I exactly identify which copies are bricked and which ones aren't?
All I know is that the inner ring reads "IFPI 9220" on messed up copies but not all of the ones I've seen had an IFPI listed on the innermost ring, only on the ring right before that, though that could be due to lighting.
If anyone could help clarify the difference, maybe with images if possible to better understand, I'd greatly appreciate it. Thank you very much in advance.

There was the Sega All-Stars re-print of SA1, that variant's got to be right

It could be, though wasn't that variant also issued by the same plant as the faulty copies? I've seen some All-Stars copies that have the same IFPI.
