That's still in 3 layers, is that okay for MAME, or should they be 'flattened' in some way first?

Tried the Donkey Kong code with SVG support, looks like it needs some work on the rendering side... smile

I'm trying to add an overlay for the ladders, but I want the entire game overlay, which is much bigger than the VFD. I managed to make it work by sort of hacking the .lay file, but what's the proper way to do something like this?
