Help getting pokemon storm silver on my home screen

I'm nodding my friend's new nintendo 3ds he bought off one of my other friends for him and he really wants to play storm silver. I really want it to be on the home screen with its own little custom inject artwork because I dont think he would like to have to go in-between twilight menu all the time. Thanks in advance for anyone who even tries to help because I am fresh out of ideas for this.
