This is a port of the arcade rhythm Guitar Freaks 2nd Mix, which is part of Konami's popular Bemani franchise. It includes all the new songs and modes from the arcade versions of 2nd Mix, along with a handful of tracks from the first game. This release is a so-called "append disc", and requires the original Guitar Freaks to play. It is also possible to share data with the arcade version of Guitar Freaks 3rd Mix with a memory card.
