Displaying controls/buttons/players

[piecesof8]

I'm currently learning my way around making a layout, and I have some questions regarding displaying the controls, buttons, and players in the FE.

Here's the effect I'm going for: I would like to always display a full image of the control panel, with the controls that aren't used for the currently highlighted game faded - sort of "ghost" images for all the controls/buttons except the ones used in the game. I have this working for the most part, but as I scroll through the game list I occasionally hit a game that either a) doesn't use controls (or buttons), so that part of the display disappears, or b) possibly uses a type of control that I don't have an image for (so again, nothing is displayed). This kind of spoils the effect.

So on to the questions:

• Is there a full list somewhere of all the controls / buttons / players images that I should have so I can be sure I haven't missed something?
• Is there a way to make mala display a default image (with everything "ghosted") if none of the other images apply? I tried setting a default image for the definables in MalaLayout, but this didn't have the effect I thought it would.

Anyone else achieved the effect I'm after?

I have the default image for my control panel as part of the background image.
(I used a pic of an x-arcade tankstick as the default, since that's what I have)
If a control panel image is available, it will cover up the default one in the background.
If one is not available, you'll just see the one that's part of the background.
The marquee and screenshot work the same way.

Oh yeah, that makes sense. Why didn't I think of that?

Okay, one more question. 

I followed BadMouth's suggestion - made my "default" images part of the background image and lined up the other definables to cover them up - and that achieved the effect I was going for (thanks, BadMouth!). However...

I've noticed as I scroll through the gamelist that when I hit a 1 player game, no players image is displayed. All my other images (2p alt, 2p sim, etc.) work as expected, but when I select a 1 player game the 1p image is not displayed. Anyone else notice this?
