NEED Banjo Kazooie Save File/State Wii64

I NEED a save state or save file for Banjo Kazooie at the start of Rusty Bucket Bay with everything else 100% completed. I got this far into the game and when I went into one of the blue boxes and killed the big box monster and whenever I try to climb the ladder back out screen goes completely black and I can't do anything!

I've spent SO much time getting to this point pleeeeeaseee someone help!
