What about the CHN area ?
CHN (for CHiNa) refers to the code used for distribution in China, Hong Kong and Macao.
After introducing the console and some games in Hong Kong (see code HKG), in the mid-1990s, Nintendo decided to outsource the production and distribution of more than 60 titles to a Hong Kong company called Mani for them. Hong Kong, Macau and Mainland China markets. Some of these titles see a late reissue with the mention "For China Only" (noted FCO) exclusive to China.
These games are rather very rare but they have been imported quite a bit, especially in Europe. It is therefore sometimes possible to see them coming out on European sales sites.
We have considered that the 4 in 1 compilations are exclusive in their own right (apart from the Taito which also exists in JPN). The label visuals are very often taken from the JPN version but, apart from the 4 in 1 compilations, there are three cases where the artwork is original to the CHN version: Adventure Island 2 (the), Adventure Island III ( the) and Milon's Secret Castle. Ninja Spirit exists with a sticker stuck on the label making the title much more explicit. It was undoubtedly affixed in order to make the import sale of the game easier. We counted it as a full version. Last anecdote to note, you will notice that three of the labels of the FCO reissues have square edges rather than round ones. These are the 4 in 1 Hudson and 4 in 1 Nintendo as well as Super Mario Land.
