er... I'm thinking...

use custom firmware 5.00 m33 and a computer...

then custom firmware extender and remote joy...

turn on remote joy... start recording video...

start the game... turn on custom firmware extender and start turning off audio channels....

then turn them on one by one and when you find the audio channel you can have only that one on and then make the noise...

save the recording... extract the audio from the vid... then crop the audio... and then convert it to wav...

done...

that's all I can come up with atm... srry :/

you could see if the game has the sounds just lying there inside it but I'm sure you tried that....
