- 这首曲子的数据可以在beatmania 5thMIX的HDD数据当中找到，但是它始终没有收录在beatmania系列，反倒是几个月后收录到了beatmania IIDX 3rd style。
- 《Hitch Hiker2》的DP ANOTHER谱面
- 《電人イェーガーのテーマ (Theme of DENJIN J)》的SP ANOTHER谱面
- An English language version of the eAMUSEMENT login screen is present in the data, along with the translated graphics from beatmania IIDX 14 GOLD's U.S. location test.
- Foundation of our love / dj TAKA feat.ASAKO
- Pink Rose / Kiyommy+Seiya
- Both songs were at one point listed on the official website for the game. Neither song made it to the final version of the game.
- A copyright screen for North and South America is present in the game data, hinting that an American release for Resort Anthem was considered. This screen is also present in the data for beatmania IIDX 19 Lincle unchanged, presumably left over from the previous game.
Although tricoro was the first beatmania IIDX game to not have EXPERT MODE, graphical data for this mode on the MODE SELECT screen can be found unused in tricoro's HDD. However, no further data for this removed mode has been found, so it is currently unknown if it can be forced to work by hacking.
- Sound and HDD data for the song exists in tricoro, but it has no notecharts and was never made playable, being the only unused song with sound data that didn't appear in any of the following IIDX games. This might be attributed to its composers, NAOKI and jun, both leaving KONAMI in early 2013.
No volume 2 of the tricoro ORIGINAL SOUNDTRACK album
- The beatmania IIDX 20 tricoro ORIGINAL SOUNDTRACK Vol.2 album was never released; the closest thing to it is the second disc of the beatmania IIDX 21 SPADA ORIGINAL SOUNDTRACK containing the remaining tricoro songs, but the release's product page never mentions that it is the second volume of the tricoro OST. The long versions of the tricoro songs that made it to the beatmania IIDX 21 SPADA ORIGINAL SOUNDTRACK caused long versions of some SPADA songs to be delayed due to lack of space (some of them made it to the beatnation RHYZE vs HARDCORE TANO*C album).
- The final cutscene of the ぼくらの宇宙戦争 event mentioned a final battle against the joker villains to be coming soon, which further suggests that a true final event for tricoro was planned. This final battle only happened almost two years later, in beatmania IIDX 22 PENDUAL's Qpronicle Chord event.
POINT ZERO's overlays
- Placeholder graphics for overlays for POINT ZERO can be found on the tricoro HDD. As the dummy images used as placeholders only show numbers, it is currently unknown if POINT ZERO's jacket was based on the scrapped overlays for the song.
灼熱Lost Summer Dayz / DJ Mass MAD Izm* vs DJ YOSHITAKA
- The original sequel to 灼熱Beach Side Bunny, titled 灼熱Lost Summer Dayz and made by both DJ Mass MAD Izm* and DJ YOSHITAKA at the time, was supposed to come out in Summer 2013 according to DJ Mass MAD Izm* himself, however nothing came out of it; it was likely the initial final boss of the クプロ・ミミニャミ・パステルくんのみんなで宇宙戦争!! event. This was supported by data of a collaboration song between both artists found on Pop'n Music Sunny Park, with said song's ID being replaced by Zirkfied afterwards. A reworked sequel of 灼熱Beach Side Bunny involving only DJ Mass MAD Izm*, titled 灼熱Pt.2 Long Train Running, would then appear two years later on beatmania IIDX 23 copula.
beatmania IIDX 21 SPADA is well known for its unfinished status. Event content being cut or not added altogether due to DJ YOSHITAKA becoming the producer midway throughout the game's life cycle and pushing for another IIDX title, and PASELI features, might have ruined plans due to the modified EXTRA STAGE restrictions.
Qprogue had a convoluted development, originally just having seven original songs and two CS crossovers (お願いアインシュタイン, Pharaoh, ra'am, Hypersonik, refractive index, RIZING YOU UP, Unicorn tail, with 煉獄のエルフェリア as the last boss), just like beatmania IIDX 20 tricoro's main event format.
After the second phase, Qprogue was supposed to get a third and final one themed after the fire island seen at the end of Qprogue DX. Map data of said phase was made but was eventually purged (including all its references) once Qprogue DX was added; Qprogue DX is referenced as "phase 4" in the data, proving that a "phase 3" was skipped.
It was supposed to house, aside some CS crossovers, at least into the battlefield and M.D.Injection, explaining why they were the only Qprogue DX songs aside 煉獄のエルフェリア to have overlays. It was also going to have Broken Sword as a sub-boss prior to 煉獄のエルフェリア. Placeholder images for the Broken Sword mini-boss battle in the fire island was left in the data (with the boss itself implied to be Tuonetar given the location and following the Last Dance story).
The third phase eventually did not happen and both it and a whole second unlock event were replaced by Qprogue DX as a last-ditch effort to quit development on SPADA and move to PENDUAL. Most of the songs and CS unlocks of Qprogue DX were likely part of this cut second event. PENDUAL's Q-Pro data referenced an "Elferia" army and an "Imperial" army which might have been the focus of the second event. 煉獄のエルフェリア could not have been the real final SPADA boss song as there wasn't a L.E.D. one yet (the only IIDX style without a L.E.D. exclusive unlock since L.E.D. himself started to make them in the series), who at that time was always in charge of final boss songs.
Interestingly, compared to other IIDX events, Qprogue's medal list did not sort songs in the order they were unlocked within the game - it was either random or sorted by when they were added to the data. Even more strangely, SUPER STAR -MITSURU- Perfect Revival medal entries were part of Qprogue's list, which added even more questions to the weird nature of Qprogue's development.
Overall, the only known song that was cut from Qprogue was Broken Sword, which premiered in PENDUAL instead.
Spada†leggendaria saw an eighth, truly final song being cut. A result banner showing the Spada†leggendaria chamber from above alongside all seven swords (including the usual "Spada†leggendaria - SECRET MUSIC UNLOCKED" text) was left unused in the data. This song is wrongly assumed to be Broken Sword (which was part of Qprogue instead) and there is no info on what it could have been.
It was likely going to be a ONE MORE EXTRA STAGE song (while SPADA ended up having none, it still had image text for it) but the newly introduced PASELI features in SPADA probably caused issues, and so the idea was dropped, leaving Verflucht as the final song of the event and last overall exclusive song of the style.
Phase exclusive song system
One of PENDUAL's core features was songs being exclusively playable in only the PRESENT or FUTURE phases. Aside the default exclusive phase songs being part of the Chrono Chaser event's unlock requirements, no other ones were added in the game and there was no development whatsoever on this feature. PENDUAL's sound direction comments mentioned more emphasis on the PRESENT/FUTURE phases by each director.
Chrono Chaser was likely going to have a more regular cycle than what eventually happened in reality, as Say YEEEAHH and Reflux, made available late in June 2015, were instead added in November 2014. Negative reception of Chrono Chaser's extremely vague unlock system was what likely put the event on a long hiatus. After PENDUAL, IIDX went back having secret extra stage events like LIMIT BURST and Spada†leggendaria.
- Despair of ELFERIA's boss overlays data contained unused sprites for a second form; they looked identical to the last form of 煉獄のエルフェリア's boss, except colored differently.
- 共鳴遊戯の華's LIMIT BREAK boss attack sequence was going to feature every joker villain, as images showing their names were found in the overlays data. Strangely, the data also contained an unfinished sketch image of Lopica (共鳴遊戯の華's main boss character).
Even though there were no clear evidences of Mystery Line being unfinished, it was the only IIDX regular event where you couldn't achieve a Platinum Tran Medal since their introduction but it also didn't have a Gold one either. The event's medal list in the files contained additional, unobtainable medal entries that had the same unlock requirements (unlock three Mystery Line charts) up to nine more songs; the entries felt more like placeholders, as the devteam just added songs to the event until the end.
Compared to any other regular IIDX event in recent styles, Mystery Line also did not have any sort of ending or congratulation message. L.E.D. announced a collaboration song with 黒猫ダンジョン before copula's release, but it never saw the light of the day - Tomosuke's only appearances in copula were crossovers, while L.E.D. did not appear in Mystery Line.
- Text related to Double BEGINNER can be found in the game data. However, this difficulty has never been available in an arcade title, and only a handful of songs have had Double BEGINNER charts in CS titles.
- Full data for Fire Beat exists inside the game, including charts, keysounds, a generic video assigned to it, and a listing inside the game's music ID database. It is speculated that the song was intended to be added alongside an event challenging players to beat top-ranker DOLCE.'s scores on the song; the event was held using beatmania IIDX ULTIMATE MOBILE instead. The charts found inside HEROIC VERSE are also different than the ones used in ULTIMATE MOBILE, possibly being a pre-release revision.
SHADOW REBELLION.VI and VII
- SHADOW REBELLION is the EXTRA STAGE system of beatmania IIDX 27 HEROIC VERSE. It was originally planned to have eight parts, but it was later modified to have seven instead. After resuming the event in June with STOIC HYPOTHESIS, the next part was originally set to be イリィガル・ベイス・メディスン. This song was mistakenly revealed in the game's official website for a short period of time in July 2020, which was when it was scrapped and replaced instead by the seventh SHADOW REBELLION song, 魅惑のYUMMYスイーツ. The reason for this change is unknown.
- This is evidenced by the unused results screen for SHADOW REBELLION.VII, which shows the Pastel-kun Q-pro from 魅惑のYUMMYスイーツ in front and the six other SHADOW REBELLION Q-pros behind it, including Shizuku Yamashina (who was the character for イリィガル・ベイス・メディスン).
- The modification date for the results screen of SHADOW REBELLION.VII is much earlier (July 2020) than those of VI (August 2020) and FINAL (October 2020), implying that the plans were changed around July 2020.
- Dummied out data for イリィガル・ベイス・メディスン's Shizuku Yamashina Q-pro parts can be found in the game.
- Early concept art showed different songwheels, one of them eventually was used in 5thMIX, and another in UNIVERSE.
- According to an interview by Aaron Chmielowiec (from the website aaronin.jp) with a former DanceDanceRevolution staff member, DanceDanceRevolution 4thMIX PLUS was going to have its system upgraded to allow for 60 FPS instead of the usual 30 FPS during gameplay. This idea was not implemented until the next release as the developers wanted to have a more stable engine with less bugs.
- According to an interview by Aaron Chmielowiec (from the website aaronin.jp) with a former DanceDanceRevolution staff member, DanceDanceRevolution 5thMIX was going to include SOLO stepcharts, but the idea was cancelled due to negative feedback from players.
- Mockup screenshots showed songs from previous mixes, which were cut in the finished product as well as a different song banner for NORI NORI NORI.
- Freeze arrows also had a judgement of Freeze!.
- According to an interview by Aaron Chmielowiec (from the website aaronin.jp) with a former DanceDanceRevolution staff member, the screen filter option introduced in DanceDanceRevolution X was going to appear in DDRMAX. However, the graphics team didn't like the idea of the artwork being covered.
- As the first DanceDanceRevolution game to introduce the MARVELOUS timing judgment, it was originally intended to be used in all modes. However, negative feedback towards its usage in location tests resulted in the idea being scaled back. In the final release, MARVELOUS only appears on courses.
- MARVELOUS timing would finally be added to all modes in DanceDanceRevolution SuperNOVA2.
- Early in EXTREME's development, there were several rounds for fans to vote on a BEMANI crossover to add over to the game. Nominees included Across the nightmare, Cat Song ～Theme of UPA, DJ BATTLE, FLOWERS for ALBION, Morning Music, THE SAFARI, Threshold Lebel, Waza, and WITHOUT YOU AROUND. The winning song was Across the nightmare, and to date none of the other nominees have ever appeared in another DanceDanceRevolution title.
- Unused data for NEMESIS can be found in the data.
- The demo featured no foot-scale, just like its arcade counterpart.
- The beta showed a interface resembling the arcade version, as well as featuring dance characters from Party Collection.
- Sweet Sweet ♥ Magic was going to be featured on this game. It made it into the following game instead.
- Information for White Lovers can be found in the game's data, but is otherwise inaccessible.
- References for One More Time by Daft Punk can be found on the DanceDanceRevolution master song list. While it never appeared in that series, it later appeared in REFLEC BEAT.
- ULTRAMIX was initally planned for the PC, and was meant to be a sequel to DanceDanceRevolution (PC). Screenshots of this game resembled more of its predecessor, and featured a new cast of dancers. However, it ended up shifting development to the Xbox, and the overall design was re-worked. This may explain why ULTRAMIX had very few new songs, due to its development.
- Early concept art featured a songwheel similar to that of the previous ULTRAMIX.
- Early gameplay videos showed EMI using LADY's body and a more revealing outfit.
- Drivin' appeared in a screenshot in ULTRAMIX3's website, and later in ULTRAMIX4's manual. However, the song finally appeared in DanceDanceRevolution SuperNOVA, suggesting the Japanese arcade team wanted the song to debut in the arcades first.
- In the E3 demo, the songwheel was very different and Listen To Your Heart Furious F. EZ Radio Edit used BROKEN MY HEART Cusimo & Co. Starlite Remix's graphics.
- Senses was originally going to appear in this game until it got replaced by its remix.
- It also appears that Alice's music video was going to be used in-game as evidenced by the jacket using a still from said video.
- In a beta demo, what was shown originally was very different from the final product. It initally featured AFRO and EMI in the character lineup, and the dancer models were adult-sized unlike in the final version where they were smaller. Routines and graphics were carried over from DanceDanceRevolution MARIO MIX. It was also to feature CHALLENGE difficulty.
- The game initally used the classic 1-10 scale on its development, and lacked CHALLENGE charts.
- There are some placeholder graphics and sounds from the previous game as well.
Changes from E3 2009 version
DanceDanceRevolution (PS3) was announced at E3 2009. What was shown was drastically different from the final game. The interface resembled more of DanceDanceRevolution X2, and had dance stages and characters in it. It also featured Octo-Mode which made it into the final game, but only on CHALLENGE charts. It was also to feature custom themes, Edit Mode and DLC from all the mainline arcade games up to this point. While the DLC made it into the finished product, the song packs were based on the US PS2 releases instead. The songlist was also based on DanceDanceRevolution HOTTEST PARTY3 as well.
Evidence for several DLC packs that were planned but never released can be found in the game's data, including Greatest Hits packs based on the following DDR CS games:
- DDRMAX -DanceDanceRevolution-
- DanceDanceRevolution EXTREME CS (America)
- DanceDanceRevolution EXTREME2
- DanceDanceRevolution X CS (America)
- DanceDanceRevolution HOTTEST PARTY
- DanceDanceRevolution HOTTEST PARTY2
- DanceDanceRevolution HOTTEST PARTY3 / DanceDanceRevolution X2 CS
- DanceDanceRevolution ULTRAMIX series
- DanceDanceRevolution UNIVERSE series
- DanceDanceRevolution (2010)
- In one of the trailers for this game, there was a different interface shown alongside from what was shown in the final game. The interface resembled that of Dancing Stage Fusion. This may imply that Fusion's interface might've been the original/ beta interface for this game instead.
- MAX.(period) and Colors Midihead's Sapphire Mix were slated to appear in the game, as evidenced by the master songlist.
- Only MAX.(period) would appear later in DanceDanceRevolution (2014) as the ENCORE EXTRA STAGE song of the Replicant D-ignition event.
- Mockup screenshots show songs that never made it into the final game, most of them were from the ULTRAMIX series.
- Data for CUTIE CHASER (MORNING MIX), DYNAMITE RAVE, ON THE JAZZ, Red Room, Brilliant R•E•D, ORION.78 ～civilization mix～, Keep Ya Body Movin', Senses, and Istanbul Café can be found in the game's files, including complete background videos; however, the songs are found nowhere in the final game.
- In an article, a picture from the game showed a dance stage that never made it in the final game.
GuitarFreaks & DrumMania / GITADORA
- KHAMEN BREAK -SDVX Infinity MashUp- / くふおー effected by Megacycle
- Full data can be found in the jubeat prop files, and its song ID is among the jubeat prop songs. It would go on to appear in jubeat Qubell.
- Pop'n Music 2 song what i want (EURO MIX) was originally going to be revived for the Euro Course (ユーロコース), making it into the location test version of the game. The final game however, replaces it with Bit of Love, with what i want (EURO MIX) not being featured in the game at all. This change was reverted in the console version of Pop'n Music 6, though.
- the KING was planned to be in the game, dressed up as either a chef or fast food employee. He never made it to the final version of the game.
Planned URA charts
References to 3P palettes for risette, SANAE♥chan, and S・8・TARO can be found on the Pop'n Music data, named with the same preffix for the 3P palettes used in URA charts. Of these three characters, the latter two have, besides their respective portraits, proper colored sprites as well. Those can be seen in this video.
EXPERT MODE and planned theme
Much like beatmania IIDX 20 tricoro mentioned above, Pop'n Music 18 せんごく列伝 was the first Pop'n Music title with no EXPERT MODE since its introduction. However, graphical data for this mode can be found on the HDD, revealing that the original theme for Pop'n Music 18 was city/town based, not unlike TUNE STREET. This suggests that EXPERT MODE was dropped early on the game's development.
There is placeholder data for EXPERT MODE courses, which uses THE MOVIE's courses, further suggesting that the mode was dropped before the final theme was decided.
- Sunny Park场测时曲目是没有横幅的，不过后来考虑到依靠横幅找歌的玩家，实际稼动时又恢复了横幅。
- According to the second page of this うさぎと猫と少年の夢 article, the game was originally going to have a diner theme, not unlike Pop'n Music 9's café one, before the staff went with a steampunk layout.
- A placeholder image for a new portrait for SHOKO can be found among the Pop'n Music うさぎと猫と少年の夢 characters. However, given that there are no placeholders for her new animations in the data, it would likely recycle either her fragments or リメンバーリメンバー animations.
- Real / Aya
DJ YOSHITAKA Song Remix Contest
On October 19th, 2016, it was announced that a remix contest involving songs composed by Yoshitaka Nishimura was planned to be held.  To date, there has been no other news or mention of the contest and it's been speculated that it has been scrapped entirely.
- Data for several BEMANI crossovers can be found in the game files, but none of these songs were ever added to the final version of ミライダガッキ FutureTomTom Ver.2. Notably, all of these songs have appeared in the DanceDanceRevolution series (except Burning Heat! (Full Option Mix), which has a shorter remix featured in that series instead), with several being added to the series in DanceDanceRevolution (2014). The sound director of the ミライダガッキ FutureTomTom series, Yuichi Asami, would go on to become the sound director of the DanceDanceRevolution series starting in DanceDanceRevolution A.

Albums / Contests / Etc.
- beatmania IIDX 20 tricoro song Re:GENERATION was originally written for the album, but didn't appear because it wasn't 180 BPM, nor a remix of a previous BEMANI song.
