So I worked on my Vertical Cocktail Groovy Arcade system and got it working very well of USB boot.
Moving back to my Horizontal Neo Geo themed Hyperspin Horizontal cab. Just capped the Nanao and it looks beautiful
I wonder if there is a way to get rid of the black bars on top and bottom on any 224 horizontal arcade games. The Arcade VGA with Groovy Mame shows a resolution of 240 x 240 as its lowest resolution.

any tips to get this to fullscreen.
