@Zigurana
As someone who understands ES way better then I do was my explanation on the z-index correct? -
@Syhles Sure, I think it makes sense like that.
Looking at it from a procedural point of view:
ES will render the elements ranked by their z-index, starting with the lowest value (i.e. 0 for background images), and elements with higher z-values can blot out elements with lower z-indexes when they overlap on the screen.

Wow, didn't expect to wake up to this many replies. I'll be back shortly to answer your questions and show a video of it action.

Looking really forward to that video. -
@Zigurana I got it

Below is a video showing the gamelist working. It also shows it working with a patterned background (slightly more complicated but the same principle).
@Syhles is correct, everything is layered. So the setup is you set the gamelist z-index to render at the back, next you have the overlay image rendering on top of that (z index higher than gamelist), and in my example the background renders above everything else (zindex higher than both the game-list and overlay.
The actual overlay image in my first examples is a graphic designed to cover exactly a single line in the game-list, however I use the <tile>true</tile> tag to repeat it vertically 9 times.
This works well if the background is a single colour but things get slightly more complicated if you have an image or pattern in the background. To make that work your overlay needs to be a duplicate of the backgound but with transparent areas for the game-list to show through.
So first you would have your background:
Next the gamelist
And on top of those your overlay (copy of background with alpha transparency.
I hope that explains it better.
The z-index is a really useful addition, so many possibilities. You may have noticed the preview screenshots have scanlines - that is also an overlay.
Regarding the border around 'marquee images', they are all edited to have that as I wanted an outline on them for this particular theme.

I'm going to be an old grump now but would you mind not cluttering up the topic with pictures of Kermit the frog.SNES mini/Nes mini/Famicom mini theme developer.

Yay I was correct it seems.On a more serious note, it would be nice if you made a more in-depth step by step tutorial for this, I followed how to do this, also didn't think of the patterned background working that easily.
Thanks for sharing how to do cool things.
-
@ruckage Thanks for clearing that up. I am sure it is jusk like Andoid z index. The only difference is android draws shadows below to show z-index thus giving it an awesome feel

I'll see if I can come up with a tutorial, most of the work needed is image editing, the xml side of things is easy.

Not sure what you mean about Android z-index and shadows. You could easily add shadows between layers if you wish though in ES.
A good way to think of z-index is as an extra axis (like 3D). You position you images using x and y coordinates which left/right, up/down repectively, so z is just in/out.

@ruckage
Thanks hope you share more inventive ways of using the z-index for things. -
Yes I agree this is great.
Android as in the OS. I am also an Android Dev so I was not sure if it was the same thing or not.

@ruckage Amazing job! Although, I can't help but think, wouldn't this be easier if the gamelist could just render an image in place of the selection bar? I might have to look into it.
-
@jdrassa Didn't you find a way for the gamelist selector to be resized? Or was that someone else?

It definitely would be easier and would be a great addition as this method has limitations and can be a little tricky to get right. If you decide to add selector bar image support I'd be first in line to test it :).

Hi @lilbud. Yeah, @jdrassa got y-offset and height working for the selector bar and it's great, if that was combined with image support it would be perfect.

HMM， does anyone know where I can download this theme?
