just found this on youtube, seems to be some kind of mobile rhythm game with Yakuza song ‘Machine gun fist’. not sure whether you have seen it before

Sure have! It’s from Taiko No Tatsujin: Portable DX on PSP. Fantastic game and region free if you import it (like I did >_>). Always loved the Taiko series but this crossover is great.

We’ve got some great gifs from it.
