Made these pictures for a buddy who requested them, but I might as well share it with the community as well. This is my Super Mario Bros international variant collection. A few years ago, I bought this collection from a fellow NintendoAger on eBay and I've continued to add to it, it's approximately 50% bigger than it was when I bought it.
This is a picture of all the front label and form factor variations, and every game that is identical aside from the back label is stacked. Especially in Europe, the only way to tell a game is from a different country is on the back label, and those are all stacked. France, for example, has a bunch of games with the same form factor and front label with back labels indicating they're from France (FRA), Holland (HOL), France and Holland (FAH), and Britain, Italy and Oceania (EAI).
Right now I'm only collecting SMB, not SMB/DH, SMB/DH/WCTM, or any other variation. Once I complete this collection, I will probably start going for all the multi carts as well. SMB/DH is the cart I played Mario on growing up, and I didn't even know there was a standalone SMB game until I started collecting, so it makes sense to go for those too eventually.
What am I still looking for? Well...
black Samurai - Samurai label, as in the ones at the end of the 5th row, but with black plastic instead of white.
South African (SAF) version - this was the Hong Kong version (end of 6th row) with an orange sticker on it that indicated South African Version.
Hit me up if you have what I need and are willing to part with it. Otherwise, thanks for checking out my collection!
