In The Groove 2: История и Развитие

In the Groove 2 is the sequel to Roxor Games') was US$2,999. There are 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 terminating 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 an un updated Andamiro made cabinet. The name appears nowhere on an upgraded 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 difficulty 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. This allows songs of any length to be played on the machine as long as the music file is still under 5 MB in size. 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 blocking the songs from being played entirely.

Some technologically savvy players have found methods of hacking the game and loading additional content onto an "In the Groove 2" machine. The In The Groove 2 arcade machine has a regular computer inside that runs a distribution of Debian Linux and a modified version of the open source StepMania software. Players who can gain access to the data on the hard drive of the computer can modify configuration files, add new features, load new songs, change graphics or artwork, or modify the behavior of the StepMania engine running in the game. The most popular methods of hacking involve booting the machine into a rogue operating system (usually a live Linux distribution such as SLAX Frodo). From there, additional songs and data can be downloaded from the USB card plugged into the Player 1 USB port, while a USB keyboard is plugged in to the Player 2 USB port 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 on the hard drive where the hacker can store songs and other data.

Due to the popularity of the franchise, some players modified the game to be played on home computers, which in 2009 became released as OpenITG, based on the code for Stepmania 3.95. In 2016, an internet user known as Taro4012 released NotITG, a fork of OpenITG which is "designed to make it easier for mod file creators to implement their ideas. It aims to preserve compatibility with all existing StepMania 3.95 and In The Groove mod files, and be the definitive environment for creating and enjoying that content.". This was released in 2016 alongside the reveal of the tournament he hosts simply called the "UKSRT" (United Kingdom Sight Reading Tournament) of which players are forced to read mod charts that they've never seen before.

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 such as the Slippers Hurricane Summer Speed event (France), 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 ultimately canceled. 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. It is referred to as "Song Pack A".
