smap is the data file that gives all the info on the sound files contained within (open it in a text editor).
If you run sdattool with the command (replace sound_data.sdat with something else if it turns out that way.
Code:
sdattool -x sound_data.sdat
sdattool is not that stable though so it may crash (which is what you have likely seen).
If that is the case and you still want to go on you will have a to rip in manually. Unfortunately for this purpose every sound file is marginally different in terms of offsets so you will have to play around a bit. Most of this is from my head so I may have got something slightly wrong.
Search for FAT (in ASCII) using a hex editor.
You will end up with a list of numbers in hex, do a byte flip on this section (the file size determining what sort: 16, 32, 64 bit etc) These numbers are the offets for the files.
Either before or after this is a list of file names in ASCII that match up to this number list.
Align the start of the list with the numbers and read off you file, the file will start with an ASCII SWAR, SSEQ or something similar (if it is bank you are out of luck) and probably be preceded by a string of 00's. You can either copy to the next file or use the 8th bit from the start of file to generate length (probably with another byte flip).
