Ok, I just bought an 8GB microSD for my M3 Real. I want to give my 4GB card to my brother who has an M3 Simply. So, does the M3 Simply support 4GB cards? When I tried it the DS got stuck on the "loading..." screen. Also, please don't just send me a link to google. I've done my research only to find that half of the places I've looked say the M3 Simply will support SDHC and the other half say the opposite. I also know that both the M3 Simply and the microSD card are not fakes. The M3 works perfectly with my brother's 1GB card and my 4GB card works perfectly on my M3 Real. I really hope I can get this to work. If not I have a 4GB card that is useless to me. Thanks to anyone that can help.
