Utility builder

Create starter MAME `.lay` files with a live visual mockup.

Enter a screen size, choose portrait or landscape, switch on the artwork add-ins you want, and this tool will sketch a basic layout preview with captions and generate a downloadable `.lay` file.

What this generates

A clean starter layout with placeholder panels and labels. It is designed to help with structure and placement, so you can refine artwork, images, and exact bounds afterwards.
