There are no official Korean language supported for this game as the page implied, original Korea version only has English. To apply Korean language, one must use the patch v1.0.9.6 for it
Topic on Talk:Aliens versus Predator 2
It should be distinguished whether the patch is official, or a fan translation. Occasionally games are updated with additional languages long after their original release. (for example Atelier Sophie added its original Japanese menus/text on PC three years later)
I have set Korean to hackable with a note that it requires patch v1.0.9.6 installed. Please confirm that it's correct.
