Hi DinohScene, apologies for not making myself clear. Actually, I followed your guide from A to Z and it worked like a charm, so thanks again for your effort. I've even installed the RT skin.
The "problem" is that:
a) on the original dashboard the games appear like in the screenshot from my previous post (grey boxes)
b) on both the official dashboard and on springboard games are all in the regular xbox 360 games category or folder, if I enter in arcade, or indie or kinect, it's empty, but I have plenty of games that should fall into those categories (on the cover it downloads I can see the "kinect" logo for example).
Weird, right? any idea on how to proceed? (the games I have are a mixture of isos converted to god and games downloaded in xex format).
Thanks in advance.
