I have VGMtrans, Cube Media Player, and PSound. I also have an iso and the nds for a game I wanna rip(Goosebumps Horrorland) I tried Cube Media Player AND PSound, but I can't figure them out for the life of me. I know how to use VGMTrans, but I can't open the nds file. I click the open icon but it does nothing, just a blank window. Even when I drag and drop it does nothing.
I have the latest version too. Can someone PLEASE help me? I'll definatly post the music when i'm done.

If it's easier, does anyone know of any other NDS music rippers? or PS2 rippers?

WHen you open VGMTrans, drag and drop a .NDS ROM into the window. After a while, it should load up all of the sample information the game has as well as the music tracks and such. Just note that VGMTrans won't be able to play all of the music, but that's where my workaround comes in:

Export the Sequence file as a MIDI, and export whatever bank it uses as a .DLS file. Open up FL Studio, import the MIDI, open up Fruity LSD, set it to port 0, you should now hear some MIDI garbage. Click the open button in the Fruity LSD plugin, and navigate to the .DLS file you exported, open that, and the ripped music should sound fine outside of potential sound distortion (can't fix that) and errors with VGMTrans' exporting.

Using this method I'd do a track rip of Nanostray 2, myself, but I don't know if certain sequences loop differently.
