Sorry if I'm on wrong on this, I think I've spotted quite a few issues with the way games are being labelled "Rev" - I have gone through them all and noted down everything I think is incorrect. Again, sorry if I'm barking up the wrong tree. Here we go;
Games which should be labelled "(Rev A)", as they already have a "(Rev B)"
Dreamkey Version 1.0 (Europe)
Games with no other Rev, so why are they labelled as "(Rev A)"?

Pro Yakyuu Team de Asobou Net! (Japan) (Rev A) (11M)

Sonic Adventure (USA) (En,Ja,Fr,De,Es) (Rev A)

Dream Passport 2 (Japan) (Rev B)
Fur Fighters (USA) (En,Fr,De,Es) (Rev B)
Phantasy Star Online (USA) (En,Ja,Fr,De,Es) (Rev B)
Games that aren't labelled with a Rev, which should be labelled "(Rev B)", as there is a "(Rev A)" already!
