I found some parts of it, but never the full game.
Might this be related to the concept of parent and child ROMs?
For example, when you want to play a specific revision of "Street Fighter II", you need the ROM that's just called "sf2" (which is the latest world revision) and then the ROM of the specific revision you want to play, for example "sf2ua" (the first US revision).
Put both zip files into the ROMs folder, start MAME with the name of the version you want to play (sf2ua) and MAME will also search for the missing files in the parent ROM (sf2).
So, if you find parts of "Donkey Kong" US set 2, but never the whole game, try to put US set 1 (or whatever the ROM called "dkong" contains) into the folder as well.
