WP7 textures are supported in the Reach-Profile that WP7 devices falls into. But XNA converts all my ressources upon adding them to a project to RGBA8, that's insane, the displays of WP7 devices are 16 Bit!
Information: WP7 SDK 7.1 (XNA 4), Visual Studio 2010
Question part 1: How can I add a RGB565 texture to a XNA project and what is the correct way to load them inside a game?
Question part 2: Is there a reasonable 16 Bit texture format (within Reach) that supports alpha with MORE than 1Bit?
Question part 3: Is the normal rendertarget (I think that's what the screenbuffer is?) already 16 bit?
