Windows Phone 7 screen capture

Has anyone successfully recorded a game running on Windows Phone 7? I’ve been meaning to record Crimson Dragon: Side Story, but there doesn’t appear to be an option to record the screen directly. I found this hack, but it looks like you need the edit the Windows registry, and I currently don’t have a Windows partition or virtual machine. … -computer/

If anyone knows of a way, let me know. Otherwise I’ll probably have to make a screener.
