Video footage of brand new arcade games can turn out to be hard both to record and to find it on the Internet. In the case of Synchronica, it's so difficult and low-spread that the first video of the series' Phase 1 Tenkaichi Otogesai song is actually a sim file for a beatmania IIDX PC Emulator!
However, the song is still there with gameplay video footage, so if you have a Nicovideo account you can check out the link above for Taku Inoue's AOU contribution.
