UPDATED: I have been testing the 6Gb SDHC card with the M3DS Real and come across a couple observations. First, I can load approx 60 games and although they are slow to launch they will play. Second, the 60 or so games total over 4.3GB because I loaded the largest games I could find megabyte-wise. I would expect a larger file-size game to load slower but even a tiny game loads slow, too. However, I still have the problem of not being able to do the following: 1) Fill the card to capacity or 2) Put more than 60 games on the card. If someone knows what the problem is please post your suggestions here. I can imagine that an 8GB SDHC will only be worse. I'm very frustrated because I got the M3DS Real/6GB Micro SDHC combo in order to load tons of games on it without having to swap out all the time.
