Hi, I am thinking about getting a M3ds Real and I am torn between which microsd card to get. I have narrowed it down to 3. One is the Kingston 2gb microsd off dell canada for $20. The second is the Kingston 2gb microsd Japan, which costs more. The third is a Kingston 4GB Microsd SDHC Card, class 4. My concern is this, is a normal north american kingston microsd card good enough to play castlevania without slow down? And is the Japanese build that much faster? I heard a couple people complain that the Kingston 4GB Microsd SDHC Card slows down for castlevania, but I would have thought a class 4 SDHC card should be faster than normal microsd cards? The 4gb Microsd SDHC costs about the same as the 2gb Japanese microsd so if it turns out that they both work equally well, I could really go for the extra space. If anyone has had any experience with these cards, can you please share your opinion? Much thanks.
