four received home ports. Two of these are GuitarFreaks games for the original PlayStation console: GuitarFreaks was released on July 29, 1999. It features a total of 18 songs: 12 from its arcade counterpart, 3 previews from 2ndMix and 3 unique songs. It features Key Disc technology to allow play of GuitarFreaks Append 2ndMix. GuitarFreaks Append 2ndMix was released on February 24, 2000. It features a total of 45 songs: 17 from its predecessor (J-STAFF is omitted), 17 from its arcade counterpart and 11 original songs. As an Append Disc, 2ndMix functions like an expansion pack, requiring the first GuitarFreaks to be loaded as a Key Disc before play. DrumMania home ports are exclusive to the PlayStation 2. The first is simply DrumMania, the drum counterpart to GuitarFreaks 2ndMix. The game's two immediate sequels were also released as GuitarFreaks & DrumMania: DrumMania was released on March 4, 2000, as a launch title for the PlayStation 2. GuitarFreaks 3rdMix & DrumMania 2ndMix was released on September 13, 2000. GuitarFreaks 4thMix & DrumMania 3rdMix was released on September 20, 2001. No home ports were released for the seven other System 573 sequels. Instead, songs from these arcade games are included in future titles for the PlayStation 2: the Masterpiece series, with a total of 150 songs split between two releases, and home ports of the V series, with 46 revivals split between three releases and unavailable in Masterpiece. V to V3 (2005–2007) In 2005, the GuitarFreaks & DrumMania series was upgraded to Bemani Python 2 hardware, which is powered by the PlayStation 2, the same hardware that later became used in the Dance Dance Revolution SuperNova series. This eased the development of home ports, which saw a reduced song list, but functioned nearly identically to their arcade counterparts. Three versions of the guitar and drum games utilized this platform: GuitarFreaks & DrumMania V was released on February 23, 2005, for arcades and March 16, 2006, for the PlayStation 2. The arcade version features 271 songs: 118 new additions, 125 from the previous version (« super "shomin" car » was removed) and 28 from older versions. The home version of V is limited to 68 songs, of which 49 are from the arcade version ("Misirlou" is missing), 16 are revivals from GF5/DM4 to GF11/DM10 (excluding GF6/DM5) and three are V2 previews. GuitarFreaks & DrumMania V2 was released on November 24, 2005, for arcades
