Question about PSX scanning

[brolly]

Ok, I probably missed something important along the way, but I was just scanning my PSX set which I didn't do since like November or so and I was surprised when cmp tells me the Track 1 of a huge amount of European and Japanese games (and some USA too) have the wrong crc!
So what's going on here? What did I miss? Or is it a problem with the current dat file?

EDIT : Ok, I just figured it's not an error and that I can fix this with injector. Is there any tutorial on how to do it? Also I'd still be very interested in knowing what exactly happened.

Just run injector and it tells you what to do.
