super mario sunshine doesnt start up

[jodi850]

hello. i played super mario sunshine about 4 months ago on the dolphin. so yesterday i decided to play from the beginning all the way to the end.
but now when i start it(i updated dolphin to lastes version) the title screen is 20-30 fps with stuttering sound. and when the video starts ans i press A on my controller
it sometimes freezes or just crashes dolphin entirly.

any idea whats wrong? i tryd the things that where told at the wiki page but they dont work.
