beatmania IIDX
(alternately
beatmaniaIIDX
or just
IIDX
, pronounced "two dee-ecks") is a series of rhythm video games introduced by KONAMI in 1999. It is the direct sequel to the
beatmania
game series, and part of the BEMANI line of music games.
Cabinet information
beatmania IIDX'
s controller layout consists of seven keys (four white, three black) along with one turntable on each player's side. The turntable for the left player's side, 1Player, is on the left of the keys, while the one on the right player's side, 2Player, is on the right.
Under the 16:9 wide display are the start button, both effector and VEFX buttons, and effector sliders (or the touch screen in the LIGHTNING cabinets). After
9th style
, there is also a cardreader in order to use the magnetic/contact-less smart card of
e-AMUSEMENT
. Each series produced has a different mix of new songs and older returning songs; starting with
beatmania IIDX 11 IIDX RED
, each style has also had a different graphical theme.
beatmania IIDX features quite a few differences from beatmania, including: two extra keys, full-motion video, more powerful hardware, wide-screen display, and more powerful speakers. Three different models of the cabinet exist: a more standard one called
beatmania II
(hence why a lot of older games' generic videos have "beatmania II" in their background videos), a more advanced one named
beatmania IIDX
, and a cabinet with two screens named LIGHTNING MODEL (released on December 16th, 2019). Eventually KONAMI discontinued support for the beatmania II cabs, with the IIDX and LIGHTNING MODEL versions becoming the standard.
As of
beatmania IIDX 25 CANNON BALLERS
, two built-in cameras for hand-shooting have been added: one on the metal cage in front of the neon lights pointing at the controls, and one to the left of the screen pointing at the player(s). Initially the game would not boot up if the cameras were not attached; this was eventually patched out.
Home versions
KONAMI has released 18 home versions of beatmania IIDX: 15 on the Sony PlayStation 2 game console, one on PC, and two on mobile devices. The PS2 games are stored on DVD, and can be bought with a controller that matches the arcade version very closely. The controller's key insert is detachable, so the player may attach it as preferred on the left or the right side of the turntable. 14 home versions, from
3rd style
through
16 EMPRESS + PREMIUM BEST
, were released in Japan between 2000-2009. The series' sole North American release, simply titled
beatmania (2006)
, loosely uses
9th style CS
as the source of its interface and system BGM, but contains a completely different songlist.
Songs in beatmania IIDX are measured by a difficulty level system, which varies from game to game. Here's a list of difficulty levels by game for reference:
The gameplay is still the same as in
beatmania
, with the addition of two extra keys. There are eight columns on the screen, corresponding to each of the keys and the turntable. While playing, small horizontal bars fall down these columns, and the player must press the right key corresponding to the lane as it reaches the red line. Keys 1, 3, 5, and 7 are white, 2, 4, and 6 are blue, and the scratch lane is red. Every time a key is pressed or the scratch is played, an instrument is played to complement the song. In order to hear the song correctly, the player must get the bars on the right timing. Depending on how accurate you hit the note, you will receive a rating of your performance in real time above that note, going from GREAT (a flashing one, officially known as JUST GREAT or PERFECT GREAT, meaning perfect timing; a regular GREAT meaning very close), GOOD, BAD, and POOR (the latter for not hitting a note at all).
The typical goal of the game is to clear the song by getting the Groove Gauge to 80% by song's end; clearing a song at exactly 80% is known as a "borderline". The gauge starts at 22%, and increases/decreases depending on your performance in a song. GREATs will increase the gauge quickly, GOODs will slowly increase it, BADs will decrease it slightly, and POOR will decrease it significantly. The lowest you can go on the gauge is 2%. However, depending on the game mode, gauge requirements can change, as explained below.
From
beatmania IIDX 6th style
onward, you will also receive a grade at song's end, pass or fail. Grade level is determined by
EX-SCORE
. EX-SCORE is measured by the amount of GREATs (just and regular) obtained in a song divided by two: two points for a PERFECT GREAT, one for a regular GREAT, and zero for everything else. You will also receive a letter grade, depending on your percentage of EX-SCORE:
F: anything lower than 2/9
E: 2/9
D: 3/9
C: 4/9
B: 5/9
A: 6/9
AA: 7/9
AAA: 8/9 and higher
There is no specific grade for achieving 100% EX-SCORE.
Clear Lamps
When playing on an e-amusement account, or on any console game/
beatmania IIDX ULTIMATE MOBILE
, the game will record your scores and clear status on each song. This will be shown on the song select screen as a glowing light next to the song's title, known as a clear lamp.
Clear lamps will glow depending on the best result you obtained playing that particular song.

Difficulties
BEGINNER
This difficulty was added as a game mode in 9th style (
5th style CS
for home version). Designed for newcomers to the game, the BEGINNER difficulty uses alternative note charts that are rated from levels 1 to 3. Not all songs have BEGINNER charts.
Prior to
copula
, BEGINNER MODE was separate from the rest of the game modes. As of HEROIC VERSE, BEGINNER charts can now appear in level folders and select Dan courses.
NORMAL
/ LIGHT7
A degree of difficulty lower than HYPER. Was named LIGHT7 prior to HAPPY SKY. Near every song since 3rd style has a NORMAL chart.
HYPER
/ 7KEYS
This is the standard difficulty. Was named 7KEYS prior to HAPPY SKY. All songs have HYPER charts.
ANOTHER
The highest difficulty, ANOTHER charts range from as low as level 3 to as high as level 12, the maximum level. ANOTHER charts are near always more difficult than HYPER; even simple songs on HYPER can become notoriously difficult on ANOTHER. Prior to HAPPY SKY, ANOTHER charts were chosen in arcade installment by pressing the VEFX button when choosing a song. Also prior to HAPPY SKY, ANOTHER charts did not have individual ratings; they displayed the same difficulty level as their 7/14KEYS counterpart instead. Not all songs have ANOTHER charts.
LEGGENDARIA
LEGGENDARIA charts debuted in SPADA and cost 4 V-Discs (or one on certain days) to play. These are generally harder versions of ANOTHER charts or ported versions of Black ANOTHER charts from CS versions. Before HEROIC VERSE, LEGGENDARIA charts had a "†" or "†LEGGENDARIA" moniker after the song title and were displayed as separate songs. Not every song has a LEGGENDARIA chart, and some songs have
only
either Single or Double LEGGENDARIA charts.
Note: These are the default settings for each mode. They might be changed by the arcade operator.
This mode gives the player a song list depending on their performance on each stage, with the range of difficulty becoming easier or harder. Three songs are guaranteed as well.
STEP UP is unavailable for two players.
STANDARD

Other Modifiers:
HI-SPEED - increases the scroll rate of the note chart. The actual notes do not have to be pressed any more quickly; the scroll speed is simply increased, and the notes become further apart. Most versions of beatmania IIDX have more than one Hi-Speed setting, differentiated by numbers (a higher number means a faster speed.) The Hi-Speed modifier is traditionally abbreviated HS with the number immediately following. For example, Hi-Speed 2 is abbreviated HS2. From
beatmania IIDX DistorteD
11 IIDX RED CS
in the arcade and consoles respectively onward, HI-SPEED can be changed in-game. .5 mods were added in HAPPY SKY and
10th style CS
for arcade and home respectively. Starting with
tricoro
, the HI-SPEED settings go from x0.50 to x4.00 in 0.25 increments. Since SPADA, the HI-SPEED setting can only be changed on the main gameplay screen.
Rootage
introduced a new HI-SPEED system, temporally replacing the old one. There are 10 HI-SPEED settings, and the chart will now scroll at the same speed on a given HI-SPEED setting regardless of the song BPM, but BPM changes will still affect the scroll speed.
HEROIC VERSE
re-enables CLASSIC HI-SPEED and expands Rootage's HI-SPEED option to 20 settings.
Hi-Speed is traditionally adjusted by holding the START button during gameplay and hitting either a black or white key. tricoro introduces the Floating Hi-Speed, in which adjustments are done by one-hundredth decimal intervals by spinning the turntable in a corresponding direction. A player can switch between the classic, Rootage and Floating Hi-Speed by pressing the EFFECT button or [0] on the keypad while the Hi-Speed window is open.
TARGET SCORE - Adjust the graphs mode with a turntable. Unavailable when two people play. ARENA and BPL BATTLE target score are exclusives in both ARENA and BPL BATTLE modes, respectively.
RANDOM+ - introduced in IIDX RED and 8th style CS, this is similar to RANDOM, except that the scratch column is included in the randomization process, so the scratches usually end up assigned to a key, and a key gets assigned to the scratch. Scores don't save when this is on.
MIRROR+ - introduced in 9th style CS, this is like MIRROR, except the scratch column is included. Scores don't save when this is on.
SUDDEN (old) - notes only become visible when they enter the lower portion of the screen. The visible portion is approximately a third of the screen. It can be enabled at the same time as HIDDEN, causing the notes to briefly blink in the middle of their respective lanes.
HIDDEN (old) - notes are only visible in the upper portion of the screen (again, approximately a third of the screen). It can be enabled at the same time as SUDDEN, causing the notes to briefly blink in the middle of their respective lanes.
REGUL-SPEED - Introduced as a secret modifier in GOLD, this negates the effect of tempo changes by setting the scroll speed to a constant 150 BPM. The player can then select an appropriate Hi-Speed mod accordingly. To enable this option, open the options menu by holding Start and press the keys "2-3-5-7-4-6". Scores obtained using this modifier are not recorded.
5-KEYS - This assist modifier disables the two farthermost keys of the player's side, thus essentially making it a 5-key chart akin to the original
beatmania
. Removed in Rootage.
ASSIST NOTES / MOBILE ASSIST - reduces chords to one or two simultaneous note(s). Exclusive to ULTIMATE MOBILE, using this option counts as an ASSIST CLEAR.
