I got Super Mario Galaxy on the Wii a few days ago, and I already love it! But while I was playing, I found out that the first part of the Observation Dome music is used for Anemone3DS's banner! (aka the app that deleted my badge arcade badges and made me upset)

Once I beat Super Mario Galaxy, I will get the sequel!
I think it removes your badges so that you can add custom ones using Anome. Also, hope you have fun with those two games, they're great!
