June 2009, featuring songs recorded since the year 2000. Both games use the "Guitar Grip" controller, and allow two players to compete against each other using any version of the On Tour series, with songs being shared between versions. Band Hero was also ported to the Nintendo DS by Vicarious Visions, expanding the play to include vocals (through the DS microphone) and drumming. The drumming uses a special "drum skin" adapter designed for the Nintendo DS Lite to map the unit's face buttons to four drum pads. However, the peripheral is not compatible with the original Nintendo DS model or the Nintendo DSi. However, since the drum skin is not electronic but a rubber cover switch that duplicates certain buttons on the DS Lite, a player can simply press the buttons in time to play the drums. The game includes four-player local wireless play in a similar manner as Guitar Hero 5 allowing any combination of instruments to be used. The game has a set of 30 songs; some are from Band Hero and others are from several Guitar Hero games' set lists. Guitar Hero: On Tour does not work on the Nintendo DSi and Nintendo 3DS because unlike the Nintendo DS, they do not have Game Boy Advance slots. Band Hero is limited to vocals and drums on the two consoles for the same reason. Mobile phone versions Guitar Hero III Mobile was released for mobile phones in 2007 and 2008, and was developed by MachineWorks Northwest LLC. The base version of the game includes 15 songs from both Guitar Hero II and Guitar Hero III, and has released a three-song add-on pack every month since January 2008. The title has been downloaded by users one million times, with both Verizon and Hands-On Mobile claiming that over 250,000 songs are played a day on the platform. The two companies produced two other mobile-based Guitar Hero games; Guitar Hero III: Backstage Pass, released in July 2008, adds role-playing elements to manage the band's success in addition to the core rhythm game, while the mobile version of Guitar Hero World Tour, released in December 2008, expands each included track for play on both lead guitar and drums, mimicking the expansion of the console series to the full band. Glu Mobile developed the mobile version of Guitar Hero 5, released in the last quarter of 2009. Other games Activision and RedOctane also
