Boot Screens See the respective posts of the images for more info. Requests The latest MenuHax (formerly ThemeHax) allows a custom 3D image to display while booting. Let's start with a little how-to straight from yellows8: The input PNG for this is located at SD "/3ds/menuhax_manager/imagedisplay.png". The PNG dimensions must be either 800x240 or 240x800. The first half of the image (in terms of pixels) is for 3D-left, the rest is for the 3D-right. The 3D-right should be same as 3D-left if no stereoscopy is used by the image. So come and share those beautiful boot screens!
