Maybe someone can help me get this game playing a little better ... all other DS games play fine on my SCDS2, but Metroid Prime Pinball is troublesome. On patch it runs at about 20% of normal speed (and I checked to make sure the slo-mo option wasn't the cause), and on clean mode I still get choppy opening video and occasional choppiness in-game. Is it my microSD? --> class 4. I know, not fast, but it works ok for everything else I try.
