n-Space has shared that, when working on Heroes of Ruin, “Nintendo helped unlock extra power in the 3DS”, which they could use “for multiplayer features”. The specifics of what that means remains unclear, but seeing as the game is so focused upon its online features, the more power dedicated to them, the better.
There’s also mention of the “deep online aspects” of the game, although the only specific mention is of a companion website that will be designed with the 3DS’s browser in mind.

Interesting, so there was more power under the hood to be utilised. Reading the original source if you understand Spanish, it basically confirms Nintendo did indeed unlock portions of the 2nd core/processor to developers.
