You can do it yourself.
You Need XZP-Tool to extract your Skin to a Folder. Once done you need to edit 2 XML files (best done with Editor).
The first file is in the root of your Skin file, called Skin.xml. search for <XBOXCLASSIC> inside the file and replace the text between the 2 <XBOXCLASSIC>.
example: <XBOXCLASSIC>Indie Games<XBOXCLASSIC>
The second file is called MenuSettings.xml and is located in the Settings Folder. Search for <tab id='5' parentid='0' text='Xbox Classic'> and replace 'Xbox Classic' with 'Indie Games'.
example: <tab id='5' parentid='0' text='Indie Games'>
Thats all. Now you have to build a new xzp file with xzptool and you are fine.
Hope that helps you and sorry for my bad english.
Indie Games is Homebrew games, theirs a table called Homebrew.. If you don't like it, just rename it to "Indie Games", like I did
Why didn't you use the search, I remember telling someone this before and how to rename it.
