* First DanceDanceRevolution game to provide an extra second after the countdown timer is over to give the player a chance to press down Start button for options.

* First DanceDanceRevolution game to play back the sample of a selected song almost in an instant after selecting from previous or next song.

* First DanceDanceRevolution game to play back a random announcer message if 20 seconds of the countdown timer remains.

* First DanceDanceRevolution game to give 10 seconds (instead of 5 seconds as in SuperNOVA2) of the countdown timer remaining with accompanying warning sound.

* Obtaining an N.G. from a Freeze Arrow or a set of Shock Arrows will break the combo.

* Only DanceDanceRevolution game that can select unavailable and nonexistent difficulties.

** Example 1: The song list is sorted by series title on EXTRA STAGE. The song [[On The Break]] is highlighted and the difficulty EXPERT is selected. Thee only available difficulty for the song [[SABER WING]] is EXPERT. Switching difficulty from EXPERT to DIFFICULT and switching to the next song will select the unavailable difficulty for SABER WING. Proceeding with this condition will use SABER WING's DIFFICULT chart.

** Example 2: The song list is sorted by ABC on ENCORE EXTRA STAGE. The song [[Dance Dance Revolution (song)|Dance Dance Revolution]] is highlighted and the difficulty CHALLENGE is selected. The only difficulty for the song Dance Dance Revolution(X-Special) is CHALLENGE. Switching difficulty from CHALLENGE to EXPERT and switching to the next song will select the nonexistent difficulty for Dance Dance Revolution(X-Special). Proceeding with this condition will result in rebooting of the game after 15 to 45 seconds of no response from the game.

*** Exception from Example 2: The song list is sorted by series title on 1st STAGE. The song [[SABER WING]] is highlighted and the difficulty EXPERT is selected. Switching difficulty from EXPERT to CHALLENGE and switching to the previous song will select the nonexistent difficulty for On The Break. Proceeding with this condition will use On The Break's EXPERT chart.

* First DanceDanceRevolution game to have training mode before the game begins, which only appears on first stage. Once training mode is enabled, it cannot be disabled; this feature was not carried to X2.

Exclusive to the arcade version of DanceDanceRevolution X are X-Special Charts, which are old DanceDanceRevolution original songs with brand-new, CHALLENGE-exclusive charts. These charts are initially only playable on the EXTRA and ENCORE EXTRA STAGEs. Each mix consists of two songs: an EXTRA STAGE and an ENCORE EXTRA STAGE. There are 8 sets of songs from [[AC DDR 1st|the first game]] through [[AC DDR EXTREME|EXTREME]] (in the case of DDRMAX through EXTREME, the EXTRA and ENCORE EXTRA STAGEs are in the same pattern as the original games' songs). These charts are all listed under the DanceDanceRevolution X category, despite being old songs.

The first set of stages (for the 1st game) were added on February 12th, 2009. The other songs were added to DanceDanceRevolution X on March 16th, 2009, but were not unlocked until much later. To unlock the X-Special charts, the player must complete certain requirements for the FINAL STAGE, usually relating to the mix of origin of the song set. All the X-Special charts were unlocked for normal play on October 1st, 2009 (except PARANOiA MAX ~DIRTY MIX~ in roulette (X-Special)).
