MicroSD card speed is becoming a very important aspect of gaming lately especially with initially problematic games such as Pokemon BW, Golden Sun, 999, Sonic Colors, etc. This is not AKAIO's fault but the inevitable idea that game cartridges have the capability to have more graphics & data and require a faster speed to transfer said data. Nintendo's new AP, which is causing all of this, is being incorporated into many new games as well. Instead of compiling a list of cards that DON'T work, let's compile a list of cards that do work so that when a newbie comes along to choose a MicroSD, he/she knows that everything will work fine. How to Tell If You're Card is Good: Perhaps with this data we finally get a grasp on solid transfer speeds and have a seamless gaming experience as intended.
