DS sales trajectory exploded for a combination of new desirable hardware revision and a few strong selling software that drove the userbase growth (not just NSMB).
Be aware that Nintendo quickly phased out the OG DS, to the point that in the fiscal year that run between April 2006 and March 2007 they only shipped a measly 220K of OG DS consoles for the whole Americas.
To understand what a strong seller NSMB was on DS just think how it sold >11M in US alone.
