I, Robot/Doodle City

"Doodle City" is the alternative to the game - a drawing tool that shows off what the game's mathbox can really do. To get started, press the firing button to choose an object - all the objects used in the game are here, including the rarely seen ones that appear when you hit a Meteor in a space wave. Pressing the first player's start button switches between painting and a clear screen. Painting with an object will leave a trail of the object. The second player's start button selects between spinning the object in three axes. Pressing both start buttons together brings up a menu of more options, including mirror on the "X" or "Y" axes and six different orbit patterns. You can also turn on a recorder which plays back what you have just painted, turn music on or off, select from different colour groups, turn flicker on or off, and you even have the option to go back to the game depending on how much time you have left. However, for every minute you have spent doodling, one of the robot's lives will be taken away from him.
