Conversion of xui files to xur file format

xui to xur conversion is typically searched by users that are looking for a way to somehow alter Xbox 360 skins.  You will have to first convert .xui skin to a compiled .xur variant. There is plenty of Xbox nodding tools available that can perform this conversion, for example the now discontinued FreeSkinApp. You can probably find latest alternatives on various Xbox forums.
