Boss Rush (Ver. SN2) is widely considered one of the hardest Challenge Courses in the Dance Dance Revolution series, if not the hardest overall. As of September 25th, 2023, there are only two recorded instances of people beating this song on original arcade hardware: first by Kaze.573 on February 14th, 2017, and second by FEFEMZ on September 28th, 2018.

The arcade version of Dance Dance Revolution SuperNOVA2 was planned for release in Europe, under the name "Dancing Stage SuperNOVA2". However, due to Sony's refusal to import the original Japanese PlayStation 2 into European territories (primarily to hinder third-party companies from modifying them to play unauthorized imported games from other regions), all releases and cabinet upgrades were cancelled. The reason why this import ban affected an arcade game like DDR SuperNOVA2 is because BEMANI Python 2, the hardware SuperNOVA2 ran on, was simply a retail PlayStation 2 with added I/O boards. While Europe did receive a PlayStation 2 Dancing Stage title under the Dancing Stage SuperNOVA2 name, it was nothing more than a stripped-down version of the North American PlayStation 2 SuperNOVA2 CS game, with one new license and most of the North American licenses removed.
