ok, thank both of you!
i've updated database entry to green and added additional offset -294 for now, not to alter existing data
but this general problem remains open
maybe admins could express their opinion

[F1ReB4LL]

684-294=390, +684 and +390 are both very common values. Just a thought, though...

Update: hmm...  VX010-J1-2F V IFPI L232 -- V usually means either +390 or +684... /viewtopic.php?p=4776#p4776

Update2: https://redump.info/disc/5107/ -- this one is probably +390 (00:02:00 and 00:01:74); https://redump.info/disc/4095/ -- probably also +390; https://redump.info/disc/5267/ -- maybe +666 (if it shares the same offset with the Game CD)...

https://redump.info/disc/5577 -- r09, could you check the ringcode?

No IFPI code and no letter.

nice find F1ReB4LL!
also likely sample offsets from the start and the end of file could hint on factory offset,
on a condition that any of those would be common
like for PCE audio would usually start @0, 4000 or 4800
but more generally it's rare to extend over gaps so one could probably guess an offset after correction
so maybe we could set up an system based on such fingerprints
