In v2.2, I edited my icons.xip file to show game icons, i found out that there was a bug when adding more than 45 entries to the default.xap file within the icons.xip. That bug caused the colors to mess up on v2.2. Hope that helps.
-----------------
For v2.3, in the description above it says:
I have tried to figure this out and I still cant get it to work. Lets say I have the game "Fable" in F:/Games/Fable . I have the fable.xbx icon file in the icons.xip. How would I edit the default.xap ? This is what I tried and it didn't work:
Transform{ children [ Shape { appearance Appearance { texture ImageTexture { url "Fable" } } geometry Box {} } ] translation 0 0 300}
I am using a skin that is different from default.
