"Rooftop Run: Act 3 (Unused) - Sonic Generations" is a high quality rip of the song Rooftop Run: Act 3 from the video game Sonic Generations.
The rip features Snow halation's instrumental instead of Rooftop Run, as the melody of Rooftop Run is similar to the melody of Snow halation.
- This rip was originally uploaded on the GiIvaSunner channel on February 28, 2016.
- The GiIvaSunner version listed Jun Senoue instead of Tomoya Ohtani in the "Composer:" line of the video description, at least by March 3, 2016.
- Later, the rip "Snow halation (Instrumental) - Love Live! School idol festival" incorporated the melody of Rooftop Run.
