Twilight Princess Crash Gamecube

[hijackedhero]

Hi, I don't know as much about computers as a lot of yall do, and idk where to put this question, so here i am. Ok, I got the game to work good and everything, i am towards the end of the game, in the twighlight, at the last boss door before i face last boss, i think. I open the door, the lock falls, i run through door. Then BOOM! The game crashes... It gave me the prompt:
Invalid write to 0xf5aa2415,PC = 0x803623c8

I have since changed some settings trying to figure it out, now if i try to go through the door it says:
"IntCPU: Unknown instruction fd9c4906 at PC= 8033bda0 last_PC=812fffc8 LR = 8033c3c8"

I just have no idea.. If anybody has any experience with this problem, please help me out.
   
    Thanks

Have you tried disabling dual core?

seems like the 2nd crash is in saving the FPU context. the first crash is in a signed divide routine. so most likely bad dump corrupting instructions
