O2 BR is an offline emulator for O2Jam based on O2Jam China. It is made by the music developer team Jack Chen, but shamelessly claimed by O2 BR as their own.


Its language is Chinese but it has a similar interface with the other versions. It basically employs the same gameplay.


  • 999 rings of all kinds
  • O2MO avatar
  • offline experience

Errors and problemsEdit

  • There are only 3 MusicHalls that you can play the song in any difficulty.
  • When you exit, a website will pop-up.
  • You cannot change your avatar.
  • Upon starting the level is 100, but when you finish a song, your level drops to 30.
  • You have to make your own EMUlist (unless you downloaded from the O2BR website).
