In the Groove 2

In the Groove 2 is Roxor's dance/rhythm arcade game, and is the sequel to In the Groove in 2004. In the Groove 2 plays almost exactly like the iconic Konami dance franchise Dance Dance Revolution; four directional panels are put on a dance board pointing up, down, left, and right. The game screen displays arrows.

In the Groove 2 runs on a DDR-derived, open-source program/engine named Stepmania and is still incredibly common in arcades to this day because of its ability to play custom songs through a free-release patch. These "R21" powered devices allow players to plug in a USB drive into the system and transfer their custom or downloaded tracks to their on-stick profile, as well as save scores.
