Hello, I was wondering why this game was listed as a fan game as it isn't. It was developed by Hummer Team and published by JY Company. It had an official release. It was not a legitimate release but it isn't just some fan ROM or something. You wouldn't call a Luis Vitton bag a fanbag of Louis Vuitton.
The title of the game is also erroneous, it should be Donkey Kong 4 or Donkey Kong 4 Country, the country designation was only on a later release and the title was originally Donkey Kong 4 only as evidenced by its original carts: https://vignette.wikia.nocookie.net/bootleggames/images/4/4c/JY013.jpg/revision/latest?cb=20130508204726
and only the third release has country in it, below the title: https://vignette.wikia.nocookie.net/bootleggames/images/a/a8/DKC4.png/revision/latest/scale-to-width-down/1000?cb=20120208195014
the Chinese name is 大金剛4, Dà jīngāng 4 which translates to King Kong 4, 大金剛 being the Chinese localisation for Donkey Kong.
