The North American home release of DDRMAX2: Dance Dance Revolution, feature-wise, is a blend of its arcade counterpart with its sequel, Dance Dance Revolution Extreme, with additions such as the Beginner difficulty and the presence of official music videos.

Unused Graphics

Note: All of the following graphics can be found in DATA/FILEDATA.BIN.

Oni/Challenge Mode

While the Oni/Challenge mode was replaced by Nonstop Mode, some of its assets can still be found unused.

Attract Sequence

A leftover from the original Japanese release.

Joint Premium

Graphics for this arcade-exclusive functionality can be found among the Mode Select assets.

Song Selection Screen

A shoshinsha mark graphic, possibly intended to be displayed in songs with a rating of 2 or lower in Basic, as is in Dance Dance Revolution 5thMIX and its home port.

Despite that no long versions exist in this game, a graphic that would have likely been used to denote one exists.

Gameplay

A graphic for an unused "Freeze!" judgement, which would have likely be seen while holding a freeze arrow.

These 5thMix-styled Game Over and Danger graphics don't seem to be used.

Unused Charts

The game's .ssq files, which store chart data, hide filler and/or hidden charts, as cataloged below:

Song	Difficulty(ies)	Comment
AM-3P (AM EAST mix) CELEBRATE NITE (EURO TRANCE MIX)	Double Light Double Standard Double Heavy	Duplicates of DIVE TO THE NIGHT.
HYSTERIA 2001 Silent Hill (3rd christmas mix) SUPER STAR (FROM NONSTOP MEGAMIX)	Double Light Double Standard Double Heavy	Double Light and Double Standard are duplicates of THE REFLEX. Double Heavy seems to be an early version of ECSTASY (midnight blue mix)'s Double Challenge chart.
i feel ...	Single Challenge Double Challenge	Duplicates of MATSURI JAPAN (FROM NONSTOP MEGAMIX).

Unused Music

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: There should be some unused tracks in DATA/SOUND/SD.BIN.

The first 6 audio entries in DATA/FILEDATA.BIN are actually leftovers from both the Japanese and American home releases of DDRMAX:

Track	Audio	Description
Track 1		A segment of BYE BYE BABY BALOON, used in the Dancemania promotion sequence in the Japanese version.
Track 2		The One More Extra Stage ending track.
Track 3		The "music list" ending track.
Track 4		The How To Play background music.
Track 5		The Ranking Screen background music.
Track 6		The "Select" menu background music.
