Tetris v1.0 (Game Boy) May Have Been Released in the USA, Too.

[ColecoFan1981]

explain this better?

if your game has the number on the left and made in japan on the bottom it is v1.0 and has different music?

That is what I am trying to find out as well.

The GB was initially released here on July 31, 1989.

Again, now I'd like to see whether or not the hard stamp on the label, if ever there were one, read "05," "22" or "23" (no final "A")?
