As of Yaba Sanshiro 2 1.8.Beta with the SH-2 cache enabled, this game is now playable. One small graphics error is the animation of the word "Pause" when pausing the game (previous frames persist underneath new frames).
Hello. I tried several images of the Bug! game. Only this one shows the title screen and nothing more. Others didn't load at all and ended with message: "cannot initialize the game". :( Bug! is the only game I wanted.
