ROM Hack How would I go about extracting sounds?

[dragster215]

ive been searching around, but i cant find anything.

you could get DSlazy to extract the games archives but I dont really know if you can extract the sounds. Just try to record the sound when you hear it and voila there you have. I hope this may help you.

recording sound dont work because of the BGM behind the sound, but thanks for trying.

There is a search box the at bottom of the forum which works far better than google does most days (this question has been answered on a fair few occasions but oh well) but generally there are four ways.
Note: this is for the extremely popular SDAT format used in the vast majority of games; it is still a talking point when games come out using another sound format which even then is usually a somewhat common format like wave (Electroplankton) or ahx/ADX (TWEWY) or PCM: http://gbatemp.net/index.php?showtopic=102645 (N+).

1) and 2) did have sites/forum threads but they are not with us these days. 1) should have source with it. Those links are my 4shared site so they should be around for some time to come and please feel free to share them. ndssndext should be able to parse the standard DS file system (not sure about VGMtrans but it is no hassle to grab the SDAT file from a rom using ndstool (frontends DSLazy and DSBuff), ndsts, ndshv, crystaltile2, nitroexplorer or even by hand.

1) ndssndext:

2) VGMtrans:

What is better between 1) and 2) seems to vary between person, game and ambient temperature.

3) loopback from an emulator. As the "title" implies you take an emulator and use the loopback feature of most soundcards to record the music into a player. Your emulator should have the option to removed channels too which means no need to have the near inevitable gunshots, battle sounds, menu sounds and the like once you find which channel holds the undesirable sounds.

4) crystaltile2: not really a method per se but the program does have sound playback abilities which you can use like method 3 above. They are somewhat broken and/or fiddly for most people though.


Oh and for giggles here is the SDAT spec:

every time i open ndstool a black screen comes up, a few columns of writing come, and then it shuts.all in less than a second

 

[dragster215]

nobody else wants to try and help?

to be more specific, im trying to get the sound made when you recieve mail in the game.

 

[dragster215]

oh wow

i am pretty sure it's possible with VGMtrans. i used that to extract music from games. you need to use Audacity to record the audio.

i tried vgmtrans, but it only found the music, not the sound


EDIT: nice picture, xshinox
