I've started collecting old GB games not long ago.

I found out that there are different versions of each games, for example I have 2 versions of Sneaky Snakes: DMG-NK-FAH and DMG-NK-NOE.

I bought a couple of cartridges without stickers, and I wonder if it is possible to identify the version of the game?
