I'm ripping for myself mostly, other people are just a nice side effect.
There's always Wine and co (though to my understanding the UF's plugin doesn't work there, not sure about the Japanese one). If that doesn't pan out, there's always wavewriting (hey, there was a usenet group releasing crappy VGMTransed oneloop mp3s, so I'm pretty sure the proper ones will get done too).
And I'm pretty sure the savestate is changed from the Desmume one to SR64 (Project 64 one?).
