Well actually, I'm planning to create a front end that simulates a game: titlepage and action sequences including a 'press 1P or 2P to start' blinking message. Once a button on the CP is pressed the menu will be displayed where you can select a game.
The goal is to make the front end look like it's the default game in my cab and act like a screensaver at the same time.
At the moment it's just an idea in my head (though I already made some code to test a few ideas), so who knows when I get around programming it...
