What is beatmania IIDX

beatmania IIDX Series
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, wife-screen display, more powerful speakers. In the beginning two different models of the cabinet existed: a more standard one called beatmania II, and a more advanced one named beatmania IIDX (hence why a lot of older games' generic videos have "beatmannia II" in their background videos). Eventually KONAMI discontinued support for the beatmania II cabs, with the IIDX 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 17 home versions of beatmania IIDX: 15 on the Sony PlayStation 2 game console, one on PC, and one 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, loosely uses 9th style CS as the source of its interface and system BGM, but contains a completely different songlist.
The latest non-mobile version, beatmania IIDX INFINITAS, is a PC release of beatmania IIDX. It uses a unique interface based on SPADA.
Gameplay
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:
- beatmania IIDX→beatmania IIDX substream: 1-5
- beatmania IIDX 2nd style→beatmania IIDX 4th style: 1-7
- beatmania IIDX 5th style→beatmania IIDX 10th style: 1-7+ (8 in 10th style)
- beatmania IIDX 11 IIDX RED: 1-8+
- beatmania IIDX 12 HAPPY SKY→present: 1-12
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, 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 JUST 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.
| Clear lamp | HEROIC VERSE | ULTIMATE MOBILE | Earlier versions | Info |
|---|---|---|---|---|
| NO PLAY | No light | The song has not yet been played. | ||
| FAILED | Flickering red | Flickering blue | Flickering Green/blue/yellow/red (BEGINNER, NORMAL, HYPER, and ANOTHER respectively) |
The song was played, but failed. |
| ASSIST CLEAR | Bright purple | The song was passed with any ASSIST modifier or the ASSIST EASY groove gauge setting. | ||
| EASY CLEAR | Bright green | The song was passed using the EASY groove gauge setting. | ||
| CLEARED | Bright blue | Bright green/blue/yellow/red (BEGINNER, NORMAL, HYPER, and ANOTHER respectively) |
The song was cleared without any extra settings. | |
| HARD CLEAR | White | The song was passed using the HARD groove gauge setting. | ||
| EX-HARD CLEAR | Flashing red and yellow | The song was passed using the EX-HARD groove gauge setting. | ||
| FULL COMBO | Strobing white, blue, and orange | FULL COMBO obtained on the 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 song 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.
Note that some tracks have certain charts that sound different from the original song.

Gameplay modifiers
[NOTE: Due to the sheer number of modifiers available in beatmania IIDX, this section will divide the modifiers according to the category that each is placed in-game (as of HEROIC VERSE). Older modifiers no longer seen in recent arcade games are also described here.]

EXTRA OPTIONS
The following options can be enabled by using the numerical keypad installed in e-amusement connected cabinets.
- M-RAN [6] - If on 2-Player Mode, both sides' charts receive the same RANDOM note column order. However, the 2P side's chart is also mirrored.
- BATTLE [7] - If on Double Play, this uses the Single Play notecharts instead on both sides.
- H-RAN (SAMURAI S-RANDOM) [8] - Same as S-RANDOM, but repeat notes on the same key are less likely to occur.
- EXPAND-JUDGE [9] - Introduced in PENDUAL. When enabled, the timing windows for PERFECT GREATS and GREATS are quadrupled. Scores and clear lamps are not saved with this enabled, but EXTRA STAGE, Tran Medals, and in-game currency are still obtainable.
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 target score is exclusive in ARENA mode.
- 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.
