I've made and uploaded a new skin trying out some ideas I had whilst making the first one. I called it Tungsten, as it looks a bit metallic, plus names of elements seem to work quite well for this sort of thing, and that one doesn't seem to have been used by too many other things!
I looked at my previous design on my N8oo, and I was worried that everything was a bit too small; I could read it O.K., but it wasn't really clear. And I also noticed the sizes of the graphics could be adjusted, so I thought I would try a few things out.
I've made the preview window bigger; it's now 400 x 240px, taking up a quarter of the screen. It works fine on the game preview images, but not on the skin previews, so I don't know if this will be allowed.
The text is still a bit wobbly (g, p and y (probably q too) always look a bit out) but hopefully that can be sorted, but the text sits a bit too high on the game buttons, so unless there's a way of adding some padding above the text, I may have to rethink this design as it looks a bit weird at the moment.
I went for games on the right, and categories along the bottom to make touch navigation more natural, although I'm not sure if thit will work. I would imagine that most people loading games on PMenu will be using the D-Pad and buttons, so this probably isn't really that much of a problem anyway.
Comments welcome!
