* The ''[[VideoGame/DanceDanceRevolution DDR Extreme]]'' arcade cabinet had a difficult-to-time trick in Oni mode. When switching between courses, the song list shuffled off the screen and is replaced by the new one. By pressing the start button in the middle of this animation, the cabinet may accidentally load the correct songs for the course, but load the difficulties from the previous one. Most combinations don't produce anything special—either a crash and reboot of the machine or Heavy step charts mislabeled as Challenge—but a few courses reveal Challenge-difficulty step charts that were DummiedOut and are not playable through any legitimate means.
* Due to the way ''{{DJMAX}} Technika'''s touch screen handles touches, you can do tap notes by dragging your finger across them, and conversely, you can do chain notes by individually tapping each individual segment. Whether this is a legitimate way of playing the game is a matter of debate.
** Normally after completing the first 3 stages of the Heartbeat Set, you'll get [[ThatOneBoss "Colour of Sorrow"]]. However, if you get 75% MAX judgments or less, you'll instead play [[http://www.youtube.com/watch?v=BN9nfiiiXCg "Proposed, Flower, Wolf"]], a beginner-level song. This bug was corrected through an online update...[[BadExportForYou which you don't get if you're playing in a country that doesn't have Platinum Crew support for its Technika machines]].
* ''StepMania 3.9'' (and "3.95", the version used by ''InTheGroove 2'') has a series of bugs that allow for some serious InterfaceScrew. The most famous one is perhaps the "[[http://rhythmatic.net/phpBB2/viewtopic.php?t=19260&sid=36c1995dc196ea6e382446738321d6af Negative BPM]]" bug, which can be used to create warps, which can then be used for a wide variety of effects and tricks. [[http://www.youtube.com/watch?v=VLVWQuKo_8U It has been leveraged]] to create crazy fan favorites.
** Unfortunately, this bug was fixed on 4.0. However, sm-ssc ([=StepMania 5=]) turns it into an AscendedGlitch by providing built-in means to perform warps.
* RockBand 3, on PS3 at least: some venues have large props that the rockers sometimes stand on. There's one venue with lots of green lanterns that does not seem to have such a prop, but the game seems to think it does, so rockers will sometimes stand several feet above the stage.
