| Just turn your PSP upside down. There you go - 180 degrees rotation. :) |

| There is no built-in way to rotate the display. If your app does gu rendering with 3d transforms, you could tweak your projection matrix to do the flip. if its 2d, then your SOL. |

If you only need to flip a static screen, you can use the backbuffer as a texture, and render a polygone with it, flipped. I could also be achieved with a screen that get updated, but then you lose backbuffering.
Look at the 'rendertarget' sample. |

I see. You want another PSP above the one you're using head to head for IR transfer, but to be able to read the other screen right side up requires the display be upside down. Well, you got some good suggestions from the others. I like the one about using the buffer as a texture and rendering it upside down. Should be fairly easy and quick. |
