Does anyone know why my GamePad is dropping so many frames in NES Remix that the game is pausing itself?

Apparently region-changing on Wii U as instructed by the NH guide doesn't delete the original region's vWii electronic manual. Now we have two identical vWii manual channels with the same banner.

If any other plurals/systems on Juxt would like to be friends, we'd love to chat and play together!
