This seems like a great game. Great controls, nice graphics with pretty sophisticated transitions between the different parts of levels. It mostly runs well on PCSX2 1.4, albeit with a few frame rate drops during boss fights.
Reached the boss rush at the end of stage 2/8.
I just ordered this and a bunch of other PS2 games from Chillout Games in the UK. This game by itself was the most expensive, 24.35 GBP plus shipping.
I received it already. That was quick, only 6 days.
My disc works, although it makes a lot of noise. Reached the end of stage 2 again, but on Normal difficulty.
My new PS2 Slim totally works! What a cool little machine that is.
