Micro Machines

* Practice Mode: At the title screen, press Up,2, Down,2, 2 Left,2 x3. Now, you can select any course to race but, after finishing it, you will go back to the title screen.

* Hard mode: At the title screen, press Up, Down, Left, Right, Left, 2, Up to activate Hard mode, in which your car skids more.

* Rock hard mode: At the title screen, press Up, Down, Left, Right, Left, 2, Up, Up, 2, Up to activate Rock hard mode, which causes your car to skid even more.

* Super skid: Go to the honey puddle in the centre of the table on the "The Breakfast Bends" track and press 1+2. A sound will confirm the code. This will cause your car to skid more (like in hard mode).

* Faster vehicles: On the qualifying race, get well ahead of the pack and then stop just before the finishing line, turn around, and hold 2 to reverse over the finishing line in first place. A sound will play if you do it right, and all your vehicles will be faster.

* Explosive opponents: On the first race ("The Breakfast Bends") stop your car at the top left corner of the table and press 1+2. A sound will play if you do it right. This makes your opponents explode when they touch you.

* Infinite lives: On the first race ("The Breakfast Bends"), drive off the bottom right corner of the table forwards. A sound will play if you do it right. This gives you infinite lives - although they don't show they are infinite if you lose that race.

* Easier opponents: On the first race ("The Breakfast Bends"), drive off the top right corner of the table backwards. A sound will play if you do it right. This makes your opponents' cars slower.

* Always finish in first place: Start the "Breakfast Bends" level as usual. When the round starts, turn around and race the lap backwards (i.e. anticlockwise). When you cross the finish line you will hear a sound to indicate the code has worked. Whatever happens, you will now finish every race in first place.

* Squinky Tennis mini-game: This tip requires two Game Gears linked-up. During the Codemasters logo, hold START until a green screen appears to enter into a tennis mini-game.
