Some might notice that GBA games on the Wii U VC have a bit more in the bells and whistles department. If you're wondering why that is, we may have found the answer. Turns out Nintendo worked with M2 to get GBA games on the Wii U VC. For those unaware, M2 most recently was working on the 3D SEGA Classics lineup for the 3DS eShop. Thanks to Kolma for the heads up!
