I have a two screen bartop cab that has one screen in landscape orientation and one vertical. I have Mame setup to show vert games on the vertical screen.
In Bigbox the landscape screen is setup as the main screen,and the portrait as the secondary(marquee) screen. When using Bigbox to select games on the landscape screen, the vertical screen shows artwork for the current game. When a landscape orientated game is run, the game's artwork remains displayed on the vertical screen throughout the duration of gameplay.
However, when a vert game is run (Mame) and is shown on the vertical screen the landscape screen gets blanked and nothing is displayed. It would be ideal if the Bigbox loading artwork remains on the landscape screen.
I'm not sure if this is a Mame issue or a Bigbox issue that is causing the landscape screen to be blanked on vert games. Any ideas what is causing this (and possible solution)?
