Hello, my M3 DS Real and 4gb Micro SDHC card are running so slow that certain games lag, and a few dont load fully. Pokemon D/P/Pt/HG/SS all lag very very badly (nearly unplayable). GTA CTW freezes on a black screen, and metroid prime hunters freezes after a few minuttes of gameplay. My SD is new and has the latest firmware (FAT32) I cannot see it being a problem with the M3 as my friends SD card ran fine. Any ideas?
