FNHot,
I use a modified RetroGUI Mala interface design on my cabinet.
I'm a graphic designer so I was able to create my own layouts at both 800x600 and 1024x768.
Unfortunately, I don't have them at 384 X 224.
My menu layouts are for arcade emulators only + Future/Visual Pinball. No consoles.
I guess you're looking for extra low resolution layout (384 X 224) but If you'd like to use my layouts, I'd be happy to share.
If you like the colors and design you could always just resize them down using Photoshop or similar software.
See my YouTube video below to get an idea of what the emulator graphic menus look like:
