n64 games cause wii memory to become damaged.?

[hugphoenix]

I am trying to get Pokemon snap specifically to work, but anything i do, it always returns "the wii system memory has been damaged. Refer to the Wii Operations manual for further instructions". I have tried the latest dolphin 7064 as well as version 6204 to no avail. I also tried Star Fox 64 and Super mario 64, both failing miserably. Anyone else have this problem? On my wii i have the menu 2.0U and the mii channel v3 installed. the games are also ntsc.

Thanks for your help
