If a set isn't there, then the game isn't compatible with Saptapper and would need to be ripped manually, same situation as N64/USF. No-one's doing these kinds of rips right now.
WarioWare wasn't compatible with Saptapper, it's just that all games which WERE have already been ripped and can be found at that archive, along with those that have been manually ripped (like the two WarioWare GBA games by UNKNOWNFILE).
What exactly are you trying to do, if you don't mind saying?
Well, when I ripped Wario Land 4 (yes I know it's already been ripped), I found there were some tracks that weren't included with the actual rip you have up here. There were two Wildflower Fields tracks, and two Monsoon Jungle tracks, but one of each had no sound effects. There was a Monsoon Jungle track without the rain, and a Wildflower Fields track without the sounds of the birds and bees. I wanted to see if there was any other tracks in Wario Ware that were not included in the set here.
