Well, it's been almost a year.... do you still want these?
Technically, Super Mario Sunshine doesn't use BRSTMs, infact, it's not streamed, but sequenced, but furry bob did manage to get the sequences, and make BRSTMs.
I have all 3 of these games as BRSTMs, but just one last question... how do you want them tagged? Proper names, or original filenames? In the case of Super Mario Sunshine, they already have proper titles, such as "Bianco Hills".
Unfortunately, there's no way of getting the audio from cutscenes, since it's all embedded in the 'video' as a single 'file'. Super Mario 64 got one, Super Mario Galaxy got one, Super Mario Galaxy 2 got one.... why no Sunshine soundtrack, Nintendo?
Here's Super Mario Sunshine (courtesy of furry bob):

It contains every song in the game, except the cutscenes.
For the stages, there are 3 versions:
Normal
Normal with Yoshi drums
Medley of the first 2 versions (like how it is in Super Smash Bros Brawl, and the Nintendo Sound Selection and Happy! Mario 20th CDs)
It also contains unused Yoshi variations for the Bonus Stages, and Noki Bay -- did Delfino Casino ever have Yoshi in it? Because there's also a Yoshi variation of that. Infact, only Sirena Beach doesn't have a Yoshi variation of all the main themes.
