Warbird, you're the best.

I might end up writing an article for the site I work for (Gamernode.com) and, with your permission, I'd like to use your translation. You'll obviously be credited.

Now, I only have two concerns:
First concern (which would actually be a great thing) is that apparently you can store up to 100 downloaded songs on your card. The save file for any DS game is like 256kb, I believe, and the average song is about 24kb. This means that, unless they're doing some incredible compressing, the card MIGHT have different hardware inside to support larger saves. This means anyone trying to emulate the game won't be able to. (Which would be awesome.)

Second concern: I'm not sure if Americans will be able to download the Speaker Channel, considering the shopping channel in Japan is greatly different than the one in the States. I'm hoping we'll still be able to, but if not, that'd be a shame. I don't think we'll have any problems downloading songs from their Japanese servers, though.
