"Moero! Nekketsu Rhythm Damashii" contains multiple enhancements over the original game, many of which were first featured in "Elite Beat Agents". These features include the ability to save stage replay data and use it later in a "ghost versus" mode, 4-player wireless play, Rumble Pak compatibility, multiple stage endings depending on the player's performance, and the ability to skip intro and epilogue sections of each stage. Also, as the player earns new ranks by achieving cumulative high score totals across all stages and difficulties, three additional bonus stages are unlocked when specific ranks are earned.
