Might need some help to make progress...

This is where I am at with version 3.0 and one issue is blocking reaching it's full potential.

I am using MAME's Border Artwork feature to implement my .png files. As far as I know there are three methods you can choose from; backdrop, overlay, or bezel. These are the characteristics I have noticed of each method:

Backdrop;
A) My phosphur pattern appears in black/really dark image areas which I don't think we want as I assume the phosphurs shouldn't be lit or that bright and also the end result looks as if we had otherwise turned the 'gamma' up.
B) My phosphur pattern does not appear in white/really bright image areas which I don't think is correct since I assume that the phosphur pattern should be noticeable. An interesting side effect of this is that the bright areas of the game image look like they are boosted.
C) The 'alpha' channel is adjustable.

Overlay;
A) You cannot see my phosphur pattern in black/really dark image areas which I think is correct.
B) You can see my phosphur pattern in white/really bright image areas which I think is correct.
C) The 'alpha' channel is not useable while using overlay mode, so we can't adjust the 'opacity' of the png file. The result is that my phosphur pattern is very overpowering and you end up with a very dark game image.

Bezel;
A) My phosphur pattern appears in black/really dark image areas which I don't think we want as I assume the phosphurs shouldn't be lit or that bright and also the end result looks as if we had otherwise turned the 'gamma' up.
B) You can see my phosphur pattern in white/really bright image areas which I think is correct.
C) The 'alpha' channel is adjustable.

So as you can see; 'Backdrop' is the worst choice. 'Overlay' would be good if the 'alpha' channel was adjustable. 'Bezel' would be good if my phosphur pattern would not be visible in black/really dark image areas.

If anyone can find a way to get either method to work perfectly then let me know and you shall be credited.

I don't know how to add files or links here as I keep getting error messages so I will have to put a post up with the files on my blog.

Edit:
The 'Alpha Channel' known issue is of highest priority on the fixit list. I have posted more indepth information in my post further down;

If you are able to come up with a solution the please contact me. Credit will be given for any help received. Maybe it requires a new MAME Artwork type that is a slightly modified 'overlay' or 'bezel'?
