There are a grip of DS games that have DSi exclusive features, mostly involving the camera, and I was wondering if those same extras work on the 3ds. Specifically for Korg DS-10 Plus it says "Optimized for DSi with 12-voice polyphony and to double the power of the original KORG DS-10: 4 analog synthesizer tracks and 8 dedicated drum tracks, increase the total number of tracks from 6 to 12." I'm assuming this uses the extra ram included in the DSi over the DS.

Here's a list of other games with DSi exclusive features: http://www.rfgeneration.com/blogs...

I believe so, yes. I went from an OG DS to a 3DS when I was playing Pokemon White 2 and it did have the upgraded DSi features on the 3DS.
