Nevermind.. I found this on the web...
I dont know how many people know about this.....
But using the template posted below you can create your own custom 360 theme / backgrounds for your xbox 360.
http://sadisticsamurai.gametrailers.com … hp?id=4200*youll have to cut out all the neon green, in photoshop the wand tool works best*
This template will line the image up just right and make sure nothing you want to see gets cutoff or blocked by the blades themself. If you still hate the look of the template you can change it... i dont care.... its yours now. just take into account the size & borders only whats shown in the empty space will appear on your screen.
You will need a couple of things to create a custom Background though....
-A 360 of course, with either a memory card or Hard drive.
-A paint or image creating program that accepts Png files. (photoshop works best *imo* , I was able to create one with Paint in windows xp but the results werent to great and the process was difficult.)
-A CD burner on your PC or a Digital Cam with Memory a expansion card and USB connection, youll also need a memory card for the camera.
How to make a custom theme/background.... This is not hacking your x360!, just a little known feature.
-Copy the template after clicking on it, Make sure to save it as a PNG file. *Dont worry, the template wont be visible on your 360 unless the blades expand due to navigation of x360 features*
-Use Photoshop to add any image you want within the border. (if you just have windows Xp paint this will be frustrating as hell, youll have to cut/delete all the neon green within the template.)
-Save the image as a Jpeg so the X360 will be able to display it as a photo.
-Place the background in either a digital cam's memory or burn it to a cd.
-Go to your X360 Media blade and connect your camera to x360 by usb or insert burned cd with background burned on it as a picture into your 360.
-Select connected digital cam or cd in 360 and select the created background image by pressing A.
-Press X and set as Background.....tada!
