The Multimedia button is used to access the firmware’s file management system. Through this application, you can access the microSD just as you would your computer’s hard drive. This application can read multimedia files such as videos, and you can play movies by downloading them and then transferring them to the microSD. You can also listen to music and read text files.
The Config button allows you to access a menu that allows you to change a few options regarding the firmware. Here you can customize the look of the firmware and choose one of the available skins. This allows you to customize your 3DS to look the way you want.
