Donald Duck Quack Attack/Goin Quackers [Gamecube] SM3 by Anterag at 1:44 PM EDT on September 2, 2018
Hi! I need a script for unpacking the streams inside that big SM3 archive which seems to contain all the sounds from the game.

Actually, there are three files in the "sound" directory: GAMESND.SP3, MAPS.SM3 & STRM.SM3

While STRM.SM3 contains all the data, I think MAPS.SM3 has the references for the files (I think, because the format seems a bit complex)

Streams may use the DSP codec.

Samples: GC

Thanks!

Sounds like the format also used in Splinter Cell games. AFAIK, nobody figured it out yet.

Ubi's map format is nothing mysterious, but it's crap, so don't think it's worth bothering.

If somebody want to implement it, here are some pointers:
- Every Single Game changes the format slighly
- usually includes Every Single Sound in the file, meaning thoushands of subsongs, and you can't really extract single files
- map is divided into sections (like, menu, level1, level2, etc), and each section is similar to Ubi SBx, but not the same.
- study Ubi SBx here
- study Ubi map info in the middle of this page
