There were a very small number of grey carts with 1.0 on them but most 1.0 carts at least in America are gold. Most grey carts are 1.2, but some have 1.1 as well. 1.1 is a general bugfixed version but also rare, while 1.2 is where all the censorship came in. Unfortunately for Europeans, all PAL versions are based on the censored 1.2 build. Due to this, grey carts are generally safe to assume are 1.2, because it is the most abundantly available build of the game, having been manufactured and sold the longest.

There are some reports of 1.1 having partial censorship as well, though these may be due to someone swapping the physical carts shell from a different version of the game.
