Beatmania II DX 14: Gold is the first model in the Beatmania series to have separate difficulties for both players. The game features over 45 new songs, some of which are unlocked over Konami's e-Amusement platform. The game runs on a new hardware platform, the Bemani PC Type 2, which is based on the Windows XP Embedded operating system.
The Beatmania IIDX cabinet consists of two turntables and two keyboards each with seven keys. This is the main difference between the original Beatmania and the Beatmania II series, with the Beatmania keyboard only consisting of 5 buttons per player. Other notable features of the Beatmania IIDX cabinet are the widescreen 16:9 display and the powerful speakers and bass platform that vibrates beneath the player's feet.
The gameplay involves the player selecting a song, with the player then having to match the notes by pressing the keys and scratching the turntable in time with the music.
