Proto:Dance Dance Revolution Extreme2

This page details one or more prototype versions of Dance Dance Revolution Extreme2.

A prototype of Dance Dance Revolution Extreme2 dated May 10, 2005 (roughly over two months before the final build) was released by Hidden Palace on March 20, 2021, as part of Project Deluge.

General

• One of the game's typefaces was slightly adjusted. This can be mostly seen in the M, N and V letters.

Proto	Final

Main Menu

• Only the Free Play mode has a proper icon.
• The "Extra" mode, which is a demo for Karaoke Revolution Party in the final release, refers to the game as "Karaoke Revolution 4". It is also non-functional, redirecting to the main menu upon selection.
• The "Lesson" and "My Room" modes crash the game.
• When a song is unlocked/purchased, no messages are displayed.

Gameplay

• The "First Stage" voice line is always used when selecting a song in Free Play Mode. In the final game, it is never called.
• Only 30 of the game's 74 songs have unique background videos. They are:
  • Licenses
    • Genie In A Bottle
    • Get Busy
    • IN THE HEAT OF THE NIGHT
  • New Konami originals
    • 1998
    • air
    • BE LOVIN
    • Can Be Real
    • CANDY
    • Colors (for EXTREME)
    • DAIKENKAI
    • Happy Wedding
    • Heaven is a '57 metallic gray (gimmix)
    • I Need You (Insideout Door Mix)
    • La Bamba
    • L'amour et la liberte (DDR Ver.)
    • Miracle Moon (L.E.D.LIGHT STYLE MIX)
    • Polovtsian Dances And Chorus
    • SAKURA
    • Sweet Sweet Magic
    • sync (EXTREME version)
    • TwinBee (Generation X)
    • un deux trois
  • Returning Konami originals
    • DYNAMITE RAVE
  • CHALLENGE-only songs
    • AFRONOVA (FROM NONSTOP MEGAMIX)
    • BRILLIANT 2U (K.O.G G3 MIX)
    • BURNIN' THE FLOOR (BLUE FIRE mix)
    • DYNAMITE RAVE (B4 ZA BEAT MIX)
    • Look To The Sky (Trance Mix)
  • Boss songs
    • PARANOIA survivor
    • PARANOIA survivor MAX
• Pressing Select enables autoplay.

Songs

• The song PASSION OF LOVE does not have proper graphics yet, recycling those of ABSOLUTE (Cuff -N- Stuff it Mix).

• There is an additional song slot between LOOK AT US (Daddy DJ Remix) and My My My. Its banner assigns it to a song with ID "lose", and it displays no difficulty and groove radar info. When selected, it plays a duplicate of ABSOLUTE (Cuff -N- Stuff it Mix). The game's song masterlist, found within the game's .ELF executable, assigns the ID "lose" to Lose My Breath, possibly the Destiny's Child song.
• The song INJECTION OF LOVE (HINA MIX) instead plays INJECTION OF LOVE(e), an English version which would later appear in Dance Dance Revolution Strike.
• Several more of the game's songs use different graphics and/or labels in the Song Selection and Gameplay screens:

Proto	Final
As The Rush Comes (Gabriel & Dresden Sweeping Strings Radio Edit)
While the title tag refers to the song as simply As The Rush Comes (GABRIEL & DRESDEN RADIO EDIT), the banner and background, which are completely different from the final version, completely ommit the subtitle.
INJECTION OF LOVE (HINA MIX)
The song's banner and background simply refer to the song as INJECTION OF LOVE.
Oops!... I Did It Again
While the title tag only has different capitalization and punctuation on the song's title, the banner and background also do not credit the song's vocalist.
Play That Funky Music
Strangely, the prototype banner lacks artist credits.
Silence (Airscape Remix)
The song's vocalist, Sarah McLachlan, is not credited in the prototype graphics. There are no artist credits in the background either. Additionally, in all graphics, "Airscape" is mispelled as "Airspace".
Spin Spin Sugar (Armand's Dark Garage Mix)
All of the prototype's graphics refer to the song as Spin Spin Sugar (Armin Van Helden Remix).
Wonderful Night (radio edit)
All of the prototype's graphics refer to the song as simply Wonderful Night.

• The Break Screen backgrounds are the same as the ones used in DDR FESTIVAL: Dance Dance Revolution.

Dance Master Mode

• None of the missions have special requirements to be cleared.
• Map B has a completely different layout compared to the final game. This layout also prevents it from being completed.

• Proper voice calls for clearing a mission have not been implemented yet; the game always calls one of the "Stage Failed" sounds.
• When starting a mission, only the area and level numbers are shown.

• In the Boss Song Completion screen, the game's title is mispelled as "Dance Dance Revolution Extraeme2", which was fixed on the final release.

Workout Mode

• Most of the character icons are placeholders. Those that are not also differ from the final version.

Proto	Final

Advanced Mode

• While the graphics and messages are garbled, the mode is mostly operational.
  • If the Dancer Display option is set to Off, the game will redirect to the Song Selection menu instead of the Course Selection menu. Selecting any of the songs crashes the game.
• The THE FREEZER, Trick, Slow-Mix, Supersonic, DARKNESS, JUMP! JUMP! JUMP!, HIGH VOLTAGE and Secret Arrow courses have not been properly implemented yet, being duplicates of other existing courses.
• The RMX of TRUTH courses are the central point of two glitches:
  • Choosing the courses on the Difficult setting freezes the game.
  • When playing in the Normal setting, reaching the songs Look To The Sky (Trance Mix) on RMX of TRUTH 1, and AFRONOVA(FROM NONSTOP MEGAMIX) on RMX of TRUTH 2, also crash the game. However, playing on Double mode is a workaround for the latter song, as an otherwise unused Heavy chart is loaded.
• Some courses use different songs:
