Quick start
Press START at the title screen, choose START GAME, then select NEW GAME and register a name in one of the four save slots. New players should run TUTORIAL from the main menu first. In the opening laboratory stages, catch the miniature Dee Dees, repair damaged machines and defeat enemies; check the level map whenever the route branches, and use the inventory to select the right gadget for each machine.
Controls
D-Pad: walk, enter or leave doors, and highlight choices. A: jump or confirm. B: context action or cancel in menus. R: punch. L: scroll through inventory. SELECT: show the level map. START: pause and display the inventory screen. The Options menu can change the button configuration, so these are the documented defaults.
