Finally got around to finishing this one. It's been in my folder for about a year now. It was mostly finished, it was just missing the percussion. Added that. Probably didn't spend enough time fine-tuning it, but it sounds pretty good as-is. Recorded it using VirtuaNES, so it's not the best audio quality.
I originally tried putting it together using a 2sf, breaking it down into the separate tracks, the same way I did that Kirby Midboss theme, but DS music isn't like SNES music. Single parts are strewn across multiple tracks and sometimes it's a mess to line them all up. I couldn't line this one up properly so I couldn't get the percussion right. So I dropped it. When I came back to it, I didn't want to go through the hassle of finding all my resource material, so I found a Youtube video and just matched the beats as best I could, and what you hear is the result. I'll find the associated VRC6 icon later.
