Problem with Pokemon Snap...

OK, first of all, I'm using Project64 version 1.6 AND a good Pokemon Snap ROM. Now, I've gotten an error that isn't listed in any of P64's help files. I set the Direct3D transformation pipeline on, and before going into the report, I set the Copy framebuffer to RDRAM on. The pictures show normally, except two things. They're all gloomy (as in have a gray shade) AND, in spite of them being perfectly fine, Prof. Oak rejects every single one of them saying that "There is no Pokemon on that picture."

Can someone help me?

If some of you didn't quite understand me, I meant that the Pokemon appear perfectly in order on the pictures, but still Prof. Oak says that there are no Pokemon on the picture. Please.... someone.... help... me and my friend tried the European ROM, the US ROM.... nothing seems to work...
