Hey guys,
Just wanted to post a progress update on this one ...
I've been working closely with Verion for the last couple of weeks to get this layout running the way he envisioned it, and I think we're pretty close to being finished. I have rewritten it from the ground up and currently have it working with all common aspect ratios (16:9, 16:10, 5:4, 4:3) and fully supports monitor rotation (none, right, flip, left) either via the host operating system or within AM settings. I've also added support for low video resolutions, tweaking the layout to look a bit nicer on a 31K 640x480 arcade monitor. Right now the lowres tweaks don't look great on 15K video modes, so please let me know if there are people out there using AM with 15K monitors and I will add some extra tweaks to help with that.
I've attached a couple of sample images below that show how the layout changes with different setups.
