I was trying to figure out what's the best kind of microSD card for M3 Real. I've tried a few different ones and they all have lag in games. I tried an A-Data 8 gig card and it wouldn't load Castlevania Dawn of Sorrow at all, it would just white screen. I had an old m3 card and a-Data was the best then for it. So I tried a patriot class 6 card and now Dawn of Sorrow loads and so does Castlevania order of ecclesia, but there is major noticeable lagging compared to my real carts of those games. I know they do not lag like that in game. So I wondered what kind of microsd card do I need to get for my m3 to work okay will all games and at full speeds?
