One of the most silly, counter-intuitive things I've faced in MAME; I guess never caring for artwork stuff and whatnot has to do with it, but this should reach MAME dev's ears the sooner the better.
Don't bug the MAME devs about this subject.
It's got
nothing to do with MAME's emulation.
Mr Do's .LAY files define the video modes that appear in the menu.
- He has donated a ton of time and effort to make the art look great and make it easy to use.
It makes sense for anyone who takes the tiny bit of effort required to understand how to select a video mode from the menu.
If you don't like the wording/video modes in the default .LAY fiile, feel free to edit it or make your own file.
