The Master System is great but it can be really confusing. Buying games online is an adventure as most sellers don't have a clue what version of the game they are selling. Most pictures of the game are just the cover of the box which in most cases is identical to the international release.
I was just going through my Master System collection and discovered that I have 5 international release games mixed in. It is pretty easy to tell the difference if the games are boxed and in hand but is there any way to tell the difference between an international release game and a US released cart only game? Is there any difference?
From what I have read a game like Choplifter (released in both markets) will run in NTSC or PAL depending on what system it is played in. Is this correct? If it is then there is no difference at all between the carts themselves right?
