When screen capturing (images, not video) your Windows Phone 7 emulator with Fraps version 3.2.3, you will notice that the Red and Blue channels are swapped (a bug fixed in version 3.2.4). An indication you have this bug is that the frame counter shows as cyan instead of yellow. This is due to the Windows Phone 7's default GraphicsDeviceManager.PreferredBackBufferFormat of SurfaceFormat.Bgr565. In Windows (and presumably on the Xbox 360) the default is SurfaceFormat.Color, which is RGB order. Windows Phone 7 uses the Reach graphics profile, which only has BGR order. Fraps 3.2.3 doesn't know that it's in BGR order, and thus saves the information as though it were RGB, swapping the R and the B.
How can you fix this?
The authors of Fraps know about this bug, and have it fixed for version 3.2.4 (not yet released). Until this is released, you can fix the images using automated batch conversion in Adobe Photoshop:
Step #1. Record a Conversion Action
Open one of the images. Open the Actions window (its tab is next to the History tab). Click the "Create new action" button. Name it, and specify which "set" it will be located within (I made my own "set" to distinguish my Actions from the existing ones). Click "Record". Now perform the following actions which will be recorded now, and later executed on each image you wish to convert:
Your Action is now saved to be used in a batch conversion. Close the image without saving since the batch conversion will handle this for you.
Step #2. Batch Convert All Images
Watch Adobe Photoshop do its thing. It may work faster minimized, avoiding all the screen redrawing as it steps through the multiple commands in the Action for each image file.
