@GtBFilms I left in as much as the cardboard filler inside as I could to help in not slide while still letting the cables get where they needed to.

We cut it so close to the screen dimentions that overall it's a very snug fit. I suppose if you were really worried about it sliding around you could drill holes in the bottom of the table to match those found on the back of the monitor where I removed the mounting plate piece. Then it would just be screwed into place. Another alternative would be to put blocks in place on the table that prevent the screen from sliding rather than relying on the cardboard. So far I havent had any problems though

@flow86 Also, you probably already figured this out, but just about any arcade classic (donkey kong, pac man, frogger, etc) that is a vertical game can be set to fill the screen and played from the vertical ends, and if you configure the cabinet style (with virtual DIP switches using in-mame GUI) to cocktail, you get the screen flipping for player 2. Works a treat. Also, you can do that with some horizontal games that support it. A game like Black Tiger can be setup that way--even though it's horizontal, they only way to enable Player 2 controls separate from P1 is to set it to Cocktail mode and it flips. This is perfect for your cabinet.

Long story short, 4-player gaming is great, but the supported games is a limited list. However, having positions around the perimeter does set you up for some ideal classic gaming. It sure beats viewing vertical games in "pillar-box" style on a horizontal screen.
