Does anyone have a lossless soundtrack (mini2sf? FLAC?) of Pokemon Ranger: Guardian Signs? I'm dying for one. The obsolete DS games section of Zophar's Domain only has the first two Pokemon Ranger games.

Still looking for this. I've come across many forgotten threads regarding this same soundtrack and hope this thread doesn't become forgotten before someone posts the soundtrack. :S

I recommend maybe making your own rips from the NDS file.

Thank you, I've already done so and have gotten it tagged with the help of another user of this forum.

Could you help me and tell me how to do that, because I'm interested in the music of the 3 Corner Shop Tamagochi games. Is the quality of those rips really good?

Check Zophar's domain for the soundrip. Use a plugin for winamp to make winamp play them, then change the output to nullsoft disk writer.
I'd just google how to do it since I'm sure I didn't explain it properly since it's been a while since I got winamp set up to play such files.
