Anyone else here make their own Wallpaper/Themes for 360 Dashboard? Here are the templates for both SDTV’s and HDTV’s, oh and I found these online so I don’t take credit for making them.
And yes you need to use all of the black border or else it will be stretched.
My current Wallpaper/Theme for SDTV: Vikki Blows does Devil May Cry 4 by YabukiStyle here on SRK.
EDIT: All you need to get these on your 360 is a USB Stick or any device the 360 can read like and Ipod, go to Picture Library and click on the device with your theme, find your theme and hit “Y To Set As Wallpaper”.
