the player compose can be transmitted wirelessly to a friend's cart(s) so they can play the song. Song list Development The game first appeared at the Tokyo Game Show in the Spring of 2001 where it was announced for the Game Boy Advance—although it was originally being developed for the Game Boy Color—under the tentative name Game Boy Music. It lacked many of the features in the DS game, such as the touch screen and wireless multiplayer, but it had a wide variety of instruments to play, and featured the same graphical style of the DS game; it also starred the game's mascot, who would eventually be named Barbara the Bat.

The expansion comes in the form of a GBA cartridge, which is inserted into the DS at the same time as the original Band Brothers card, making Band Brothers the first DS game that uses the GBA port for more than some minor unlockables. It features 31 new songs, which were chosen based on a survey posted on Nintendo's website in July 2005. The scores of the songs do not save after being played. Sequel On June 26, 2008, a sequel named Daigasso! Band Brothers DX was released for the Nintendo DS in Japan. It was released in Europe under the name Jam with the Band on May 21, 2010.
