Music theory games for the NDS?

Dear muso's and good people of the romulation forum;

I recently downloaded Rhythm and Notes for the NDS, and i was wondering if there were any more of these sorts of games available.

thanks in advance

 

Try Protein (homebrew) etc. for some or that game starting with D. Although Protein is more of a music making remixer etc.

 

thanks guys, i'll check those out
