How to rip sound effects?

[Garamonde]

I was considering ripping sounds from a Japan-only GBA game called Bomberman Jetters - Densetsu no Bomberman (that I have a sprite ripping project for) but I think it's one of those games where Hudson used their own dumb exclusive format for the music and stuff so I guess the sounds would be the same case. Would using a sound ripping program work (obviously I'm trying hard to avoid having to record every sound, especially with there being no sound test)? And what's the easiest to use?
