Beatmania II DX 17: Sirus is a DJ simulation game as part of the long running Beatmania series. The game is playable by 1 or 2 players, and features e-AMUSEMENT support where available.
Sirius adds two additional note types to the game, "charge notes", which must be held for their duration, and the "back spin scratch", a type of scratching which must be spun on one direction continuously and spun again to the opposite side at the end of the note.
The Beatmania II DX cabinet controls consisting of two turntables, and two keyboards each with seven keys. This is a 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 II DX 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.
