Advmame 3.6 bezels and screen settings issue

[pumpkinrat]

Hi Guys,

Been working at trying to get advmame 3.6 to display correctly on my 16x9 tv with bezels for the few games that I use advmame for. Could use some help.

Pi Model 3B
Retropie 4.3
Emulation Station
Advmame 3.6

I've looked at several advmame bezel posts on the forum and am still a bit lost.

my advmame.rc settings are:

dir_artwork /opt/retropie/configs/mame-advmame/advmame.rc
display_artwork_backdrop yes
display_artwork_bezel yes
display_artwork_overlay yes
display_aspect 16x9

I noticed the .rc file for advmame 3.6 does not contain the: "display_artwork_crop" option like the older .94 and 1.4 rc files.
I've gathered the "old mame artwork" files. I've attached a photo of what I'm seeing in game:

My main questions:

1. Bezel image doesn't extend the entire 16x9 screen, how can I get bezels to stretch the entire screen?

2. The game screen image to not 4x3, it's stretched L and R. - how can I resize game screen to be 4x3? I get how to position the screen, but how can I adjust size?

3. RGB scanline effects on advmame are weak, are there any scanline overlays out there for advmame that are better?

4. Are there any screen curvature settings in advmame

Any help is truly appreciated
Thanks
