In fact, South Koreans are not very interested in the North Korean language.
Taking this question as an opportunity, I looked up the North Korean dictionary.
As a result, there seems to be nothing worth considering as a dictionary yet.
However, I was able to find a site provided by the South Korean Unification Ministry.
This is a dictionary service for language comparison between North and South Korea.
https://nkinfo.unikorea.go.kr/nkp/term/skNkLangCompare.do
This site is a very small dictionary service that simply compares words.
The case of the above mentioned '겨례말큰사전' has not been completed yet.
The business of compiling dictionaries for several years has been sluggish.
If the '겨례말큰사전' is completed, it can be viewed as a complete dictionary.
