So. Acekard 2i finally came in. I tried it out yesterday (without formatting) using a 1gb Kingston microSD that was sitting around and everything worked like a dream. No lag, audio was fine, and HG even loaded. Seeing that the cart worked fine, I went out and grabbed a Sandisk 4gb microSDHC and formatted it to FAT32 with the Panasonic formatter. Most games work pretty well, but I'm having some pretty annoying issues in others. From the games I've tried, there's in-game lag in Platinum and Phoenix Wright that wasn't there on the other card, HG won't load (though, as I see, that's a common problem), and Spirit Tracks and Phantom Hourglass both freeze during cutscenes (intro in PH, princess meeting in ST--though I can't confirm that those worked on the other card) plus some audio issues throughout. So. Is there a way to work around these problems with the 4gb card or will I just have to limit myself to less storage for better performance?
