Help with sprite/audio ripping - odd file formats

[SureinDragon]

First off, let me just pray I put this in the right section. If it's in the wrong place, please let me know. Since it included questions about sound and sprites, I was unsure of where it should be placed.

With that predicament out of the way, lets move onto my real problem.

I've been delving into the world of spriting recently, and I've been researching how to rip sprites from games to make little pixel arts of my own to use for various things like cellphone backgrounds, avatars, etc, and I'm trying to get audio files to use as ringtones.
Right now, I'm trying to rip sprites from the game "Sands of Destruction" to make a background for my cellphone, and a few audio files for ringtones, but I'm having on heck of a time trying to figure things out.
First off, let me note that I DO own this game in real life, and I'm trying to extract the files from a rom I've downloaded off of the interwebs.
I've googled, binged, and researched my way to numerous tools, applications, and tutorials for sprite ripping, but all of them go over the same components that my rom does not seem to have, which leaves me in a bit of a bind. Once the rom is unpacked, I am left with two major files that I've found, .iear in a folder labeled data, and .sad in a folder labeled stream. There are three more folders, one called ParameterData with .bin folders, a romswd folder, and a movie folder with .mods files, but I don't think those have what I want.
No tutorials I have found have even mentioned these types of files, so I have no idea what to do with them. I was wondering if anyone here would know how to work with them? Any answer, even a "No one knows what to do with these" or "nothing can be done" is all I need!

tl;dr?

I want to rip sprites and sounds from Sands of Destruction, but the unpacked rom files have odd extensions that nobody mentions in tutorials and I can't work with them. These extensions are .sad (for audio) and .iear (for everything else?) Is there any way I can still extract/convert them for use?

Those sound files can be easily converted but I don't know about the sprites.
You could try TiledGGD for the sprites.

Oh, that's awesome! I'll google around a bit for a converter and for this "TiledGGD", but if you know of any sound converters I could use, could you let me know? Thank you for the advice!

EDIT: After searching high and low, I haven't found anything that can convert .SAD files, except for something called DarkOmenAudio, which I can't get to work for me, probably because its a component of some online game called DarkOmen. Still looking for advice in this section as well.

A quick google brings me to here: http://www.fileinfo.com/extension/sad
Try that Dragon UnPACKer thing and see if it works.

Edit- This shows how to convert them with that dark omen thing: http://forum.dark-omen.org/tools/audio-e...721.0.html

Hmm, I know Tinke can open .SAD files of NDS games and convert them to .WAV files when you export it. (if it isn't packed, you are lucky).

Of course, the game you have in mind needs to be supported first by the program itself (for the other files). You have to contact pleonex in this case. Surprisingly, he has an account in this place too... XD
