At Least One DS Game is Enhanced by the 3DS’s Circle Pad

Infendo

The 3DS’s circle pad actually works as an input for regular DS games. I’ve found that it’s bothersome to use it for games like Pokemon HeartGold, but it improves the control in Mario Kart DS. The circle pad is easily on my list of the top three best features of the Nintendo 3DS.

Has anyone else discovered a DS game that plays better thanks to the circle pad?
