Extracting sounds from Sonic Rush (NDS)

[PEPER]

   
I'm trying to get general game sound effects, specifically rail grinding and jumping. I'm assuming that they're all in Game_SE as shown above, but I can't open this file and while SWAR has a few audioclips, it's a select few sound effects and voice clips (none of which I'm looking for). Is there a way to convert SSAR to something readable or a plugin I can use? Not finding a lot of stuff online.

BTW this is my first time working with Tinke so sorry if I'm missing something obvious.
