So if I wanted to to give DK melee more music, using warrioware, how would I go about do that, and where and how would the code be placed, and how?
First of all, what is "DK melee"? Jungle Japes?
Well, you take the ID for WarioWare Inc -- 16 -- and replace Jungle Japes's ID -- 22 -- with it.
I'm not sure where in the code you find Jungle Japes though, so sorry but I can't help you out on where you would put this code. I would imagine it's more than likely somewhere in the "Default Stages" section of the code, and you have to replace Jungle Japes's ID with the WarioWare's ID, then Jungle Japes will have that soundtrack.
