In the Groove 2 is the sequel to Roxor Games' 2004 arcade game In the Groove. It was released to arcades officially on June 18, 2005. It is available as an upgrade kit and as a dedicated cabinet developed by Andamiro. The price for a dedicated cabinet is $9,999 USD and the upgrade kit (sometimes referred to as a "Boxor") is $2,999 USD.
There is a total of 137 songs available in the arcade version. This includes all 72 from the original arcade game, the three new songs in the home version, and 65 brand new songs, four of which are hidden and unlockable.
A lawsuit filed by Konami on May 9, 2005, asked for an injunction against the sale of the upgrade kit version. October 23, 2006 Konami and Roxor reached an out-of-court settlement which resulted in Konami acquiring the intellectual property rights to the In The Groove franchise and thus effectively terminated the distribution of the game in North America. 
In development, it was known solely as In the Groove 2. On June 18, 2005, Roxor Games officially announced the release of the game, and announced that it would add the name of Andamiro's Pump It Up line, becoming Pump It Up: In the Groove 2. However, "Pump It Up" only appears on the marquee of the dedicated cabinets developed by Andamiro. The name also appears on the title screen of a un-updated Andamiro made cabinet. The name appears nowhere on a unupgraded cabinet.
The game also features a modified interface, based on the first version but recolored red and incorporating other changes. The interface also features a new font; the first version used a generic font.
USB memory card support has been expanded on In the Groove 2, with the ability to now install revision updates stored downloaded from the internet saved onto the memory card. Several revisions have been released, most of them adjusting timing windows, fixing sync issues with songs, and fixing other bugs. However, only "r2" machines have the ability to install revision patches. Some early ITG2 machines contain "r1", which does not contain the Machine Update option. The biggest addition of functionality added with the patches was contained in "r21", which added the ability to load custom songs from the memory card.
The Novice difficulty level is a feature added to the home version of In the Groove, carried over to In the Groove 2. On this dfficulty level, all songs are rated as ones (including the hardest and fastest songs on other difficulties), and play in Novice mode places a traffic light graphic on the screen that tells players when to step. As always, two players can select different difficulty levels for the same song, but if one selects Novice, then the traffic light always appears instead of the normal backgrounds. It is also worth noting that on ITG2, Novice always forces a constant speed of 120 BPM (a "C120" mod). As a result, since C-mods disqualify scores from appearing on the scoreboards if the song played has pauses or speed changes, those songs will never have any Novice scores saved.
Rolls are a new feature. They look like spiky hold notes and usually come in pairs. The player must continually tap the corresponding arrows until the end of the roll, much like the drum roll notes in Namco's Taiko no Tatsujin. Regardless of the song's speed, rolls must be tapped at least once every 0.3 seconds.
Survival Mode is another course-based gameplay mode. The player must play a five-song course, where each song has a time limit less than the song's length. Time left over after each song is carried over to the next, and missteps deplete the time remaining - time is only added for Fantastics, with no change for Excellents and detractions for anything lower. The lifebar in this mode is not used to determine whether the player passes. Instead, it serves as a visual indicator of how much time is remaining. The game ends when the remaining time is fully depleted.
Fitness Mode is a common home version feature on dance games that is included in the arcade version of ITG2. This gameplay mode allows users to keep track of time spent dancing and calories burned.
Three previously Marathon-only modifiers - Bumpy, Beat, and Robot (a metallic gray Flat arrow type) - have also been added to the regular modifier list. In addition, a multi-colored arrow type, Vivid, has been added for colorblind players. It resembles the default arrow color scheme used in Dance Dance Revolution.
"Excellent", "Great" and "Decent" judgments are now prefixed or suffixed with a dash. A prefix (-Excellent, -Great or -Decent) indicates that the player stepped too early; a suffix (Excellent-, Great- or Decent-) indicates that the player stepped too late. In novice mode, "Way Off" becomes "Way Early" and "Way Late" respectively; in other modes, the dash system still applies.
"Stretch Jumps" have been included in double play, a jump that requires a player to hit two panels simultaneously that are farther away from each other than normal jumps, such as 1PU+2PD or 1PL+2PL.
In the Groove 2 includes more than 60 new songs in addition to the entire songlist from the previous version, In the Groove. The sequel includes new songs from established artists like ZiGZaG, Kid Whatever, Inspector K, Nina, Digital Explosion, and Machinae Supremacy. It also introduces songs from newcomers like Tekno Dred, Affinity, Hybrid, Lynn, and Onyx.
As with the original game, several artists that have released songs for Dance Dance Revolution games appear on ITG2. These include Bambee, Missing Heart, Spacekats (known as Bus Stop in DDR, with the exclusion of one member), Ni-Ni, Triple J, E-ROTIC and Lynn (Papaya in DDR). In fact, three songs appear on ITG2 that have been on Dance Dance Revolution games, though with different step charts: Typical Tropical and Bumble Bee from Bambee and Sunshine (originally Follow The Sun) from Triple J.
Of note, Wanna Do ~Hardhouse Mix~ is the only song in ITG to have a dedicated music video in-game, as it also serves as the theme song for the game.
This list covers the 64 songs that are new in the arcade version of In the Groove 2. This song list does not include the songs from the original game (although they are playable in In the Groove 2). To see those, reference the ITG song list.
The difficulties are abbreviated to conserve table space:
- N = Novice
- E = Easy
- M = Medium
- H = Hard
- X = Expert
Songs that need to be unlocked are highlighted in red. Some Expert step routines have to be unlocked separately, even though the songs they go to are playable from the start. These are denoted with an asterisk.
This list includes the five songs made playable in the home version of In the Groove. These are highlighted in green, and do not have to be unlocked in this game.

Machine Updates (Revisions)
As In The Groove 2 matured as an arcade game, Roxor released patches, called "revisions", that could be applied to the machine in order to update it, fix bugs, adjust timing window errors, and other issues as they were discovered. This list contains only changes that were officially published by Roxor Games.
Their website discussing these Machine Updates, and their respective downloads are still available on the In The Groove subdomain of Roxor Games' website.
This is the first version of In The Groove 2, and is considered to be a beta. This is the only revision of the arcade that is not capable of performing updates.
Released: July 11, 2005
- add serial number to title screen
- add coin debounce time to fix "some coin drops register multiple times"
Released: November 2, 2005
- Changed volume mixing from 90% to 85% to fix clipping problems.
- Service button must be held down briefly, to prevent accidental triggering due to electrical noise.
- Debounce all input, to fix spurious input problems (fixes extra way offs, mine explosions).
- In diagnostics, show the serial number of the drive in red.
- Fixed holding left and tapping right allows changing songs after selecting chance.
- Fixed pressing left/right while holding select to change difficulty also moves the wheel.
- Improved power selection for USB devices; may improve compatibility with iPod Shuffles.
- Fixed logo splash sound ignores Attract Sound Frequency setting.
- Improved memory card backup logic to reduce chance of corruption.
- Fixed pen drive "edit" icons in double play showing edits for single play.
- Default "premium" option is "double for one credit".

Custom Songs on Revision 21
On October 11, 2006 (a week prior to the official announcement of Konami's acquisition of the intellectual property rights to In The Groove), Roxor released Revision 21 (also referred to as r21). The patch adds a feature that allows players to play custom songs with an accompanying .sm file (see StepMania) stored on their USB card. The songs are stored in a Songs folder contained within the In the Groove 2 folder generated by the game.
Limitations to this feature include:
- The music file can be no more than 120 seconds (2 minutes) long.
- The music file must be in Ogg Vorbis format.
- Ogg music files must be less than 5 MB in size.
- Banners and song samples aren't loaded, and are thus absent from the song selection screen.
- Background images (whether still or video) aren't loaded; instead, random background videos run during play. However, background scripts that use In the Groove's background videos do work within r21.
- 50 songs maximum are loaded per player; sometimes fewer are loaded if the USB load time exceeds a certain limit.
An unofficial patch was later released online to circumvent the song length limit. It worked by changing the metadata in the header of the OGG file to make the game think the song is only 1:45 long. The program which performs this patch is commonly referred to as the Ogg Length Patch program. This allows songs of any length to be played on the machine, provided the music file is still under 5 MB in size. Playing songs that are longer than 3 minutes is looked down upon by some arcade operators due to the possibility of losing money, and in some cases bans have even been issued on players who excessively play long songs when others are waiting in line to play. The Ogg Length Patch vulnerability as well as other bugs and timing issues were fixed in R23. While R23 has timing corrections and bug fixes, it forces all custom songs to end at 120 seconds of play regardless of the use of the Ogg Length Patch.
Despite the timing fixes, Revision 23 is unpopular with the majority of ITG players. Even though some professional players prefer r23 due to the timing fixes, the strict time limit of 120 seconds was looked down upon since some official Dance Dance Revolution songs and even some official songs on the In The Groove 2 cabinet itself go beyond this time limit. Some players feel that RoXor should have implemented a system similar to Dance Dance Revolution 5th Mix (and already implemented in StepMania) in which songs longer than 150 seconds (2½ minutes) are deemed a "long version" song, which takes up two stages (two songs' worth) of the player's credit, instead of just counteracting the Ogg Length patch.
Due to the fact that In the Groove runs a distribution of Debian Linux and that the game utilizes StepMania as its engine (which has been used outside ITG for creating and distributing stepcharts for other songs), technologically savvy players have found methods of hacking additional content onto an "In the Groove 2" machine. The most popular methods involve utilizing a live Linux distribution (most methods SLAX Frodo) to boot the machine to a rogue operating system that the user has control over. Additional songs are loaded onto a USB card (plugged into the Player 1 USB port), and a USB keyboard (plugged into the Player 2 USB port) is used to type commands at the Linux console. Most of these hacks utilize an option in one of StepMania's configuration files, Static.ini, to load songs and content from additional locations other than the main song folder.
Pros & Cons
Songs loaded onto an ITG 2 machine in this manner circumvent the restrictions imposed on custom songs: the banner and song samples load on the song selection screen, the background pictures and/or videos display during gameplay, and if the song is 2½ minutes or longer, it will not be cut off. Due to the static settings which are defined by the arcade theme, no song will take up 2 rounds. This is because the tutorial was considered when developing the original ITG and was designed to use only 1 stage. Songs loaded onto a machine in this way will play regardless of if the machine's USB slots are working. This can be beneficial for tournament operators who want to load custom songs on a machine in preparation for a custom songs tournament.
However, even with these benefits, arguments can still be made against hacking the machine. Aside from the difficulty of the procedure itself and the danger of damaging the machine, one can also question the dangers of adding rogue material to a publicly available entertainment device. A measure of care must be taken as to which songs get loaded onto the machine. Often songs are pirated, and some songs aren't appropriate for all audiences. Many simfiles are not synced properly or don't have all five difficulty levels for both singles and doubles play. Some stepcharts are mislabeled or unreasonably difficult or unfair to complete. All of these factors can reduce the overall quality of the machine if care is not taken to only add high quality content to a hacked machine.
Custom songs that have been loaded onto an arcade machine in this way also have more stringent formatting requirements. Since the machine is not being used in the intended way, no safeguards or conveniences are made for the modder. The exact requirements and consequences for not meeting those requirements differ depending on the revision of the cabinet, but improperly formatted simfiles can result in empty stepcharts, warped music, or entire system crashes, all of which detract from the overall appeal of the game in a commercial institution.
In The Groove 2 tournaments are held at arcades throughout the world. Some of the most notable tournaments are NAT05 and the ITG World Cup, in which first place received an ITG2 dedicated cabinet. Most tournaments are scored on a player's dance percentage. There have been few others that have involved the use of mods, double, and even some that make use of custom songs with the R21 feature. After the lawsuit, the tournament scene began to die down, in part because Roxor could no longer sponsor local tournaments with small prizes and In The Groove paraphernalia such as t-shirts and posters. Still, there are tournaments held throughout the Americas and as of recently, Europe, today that give out cash prizes and other various gifts, such as arcade tokens, coupons, and other video games.
Due to the Konami lawsuit, a PlayStation 2 port of In The Groove 2 was not released. However, a non-final beta version of the game was leaked onto the internet. A patch is available for the PC version of In The Groove that adds the new songs and theme from In The Groove 2 to the game.
