Knowing my taste in games, Gradius WOULD end up being one of the few game series that don't work properly on it. I was surprised myself, as I remember reading that the PS2 emulation was done with a hardware solution rather than software. I can understand Gradius III & IV not working right because it was a rather obscure near-launch title that wasn't purchased by many people, but Gradius V is a much more recent game. Ah well. Hopefully a firmware upgrade can fix whatever is causing the problem?
