Hello these items you need from the main menu according to the image allowing you to show the appropriate menu items.
For example, this one for the HDMUCenter entry.
<convert type="MenuEntryCompare"> dhdmumc_mainmenu </ convert>
Just get a look, the skin on the XML revolution to line 741
looks so <Screen name="menu_mainmenu" position="0,0" size="1280,720" title="main menu" flags="wfNoBorder">
Since your problem is I can not make all the way, I can not exactly help you with your problem.
Please give me more information so I can better understand your problem to help you.
