EEC was also used in France. Got Fester's Quest with EEC on the front and FAH on the back. It might have the original from Holland too (FAH = France and Holland), but it was bought in France atleast

I have bought earlier NES games from the black series from Germany with FRG on the back, but not front. Some say that FRG stands for Federal Republic of Germany (West Germany), but that dont make sense to me. The Berlin wall fell in 1989, but games like Snow Brothers, Solomon's Key 2 and many others have FRG code on the front. These games were released years after the wall fell, so why use West Germany as code when it doesnt excist? FRG games are from Austria atleast.
I can also mention that the ESP code was also used in Scandinavia for later releases like Hammerin Harry, Robocop 3, Captain Skyhawk etc etc. Bergsala imported the games from Spain, possibly to save money. I have also found Robocop 3 ESP code in France 2 times, so i guess they imported some stuff too.
I bought a NES lot from a guy in Australia. 3-4 of these games had ITA code on them. Its possible that Australia used the same code as Italy on some games. Also possible that this guy was in vacation in Italy and bought some games or imported them to tho.
