OK, I tested the USA version if Super Mario Sunshine
Framerates were all over the place.
Outside, it was about 8-18
Videos, around 35
Level select, around 70*
Bonus levels (where you hear the really cool Mario music, and fighting pety piranha), around 15~25 FPS
No sound. However, I did notice a few weird things.
First of all, when I first got the FLUDD, it gave me a weird message like "DBAT WTF" and Fatal error; continue? I selected yes, but it froze. I went in and played again, and I didn't get that message. It also happened when I beat the boss on Delfino airstrip. It was after I saved, so I played again, and it continued. Then I played, and it was slow, but it played. Here are some screenies.
*I think the game is meant to be only 30 FPS, however, in level select, its meant to be 60 FPS. Im still figuring that out.
