My girlfriend has been playing through this game and has now come to a point where she cannot advance any further in the game (this is probably because neither of us can read japanese) and we cannot find anything online that tells us how to progress in the game. As such I would be very grateful...
@Maximumbeans, Indeed. I've been working on getting this Infecutus chip to work on my PS2. But after soldering, I realised that a plastic piece was missing from the power ribbon cable to the power and eject buttons.
