Firehawk

To activate the CHR RAM "Smiley Test" easter egg for this game, you will need to power on the NES/Famicom console while holding Up, Down, Left, Right, B, Select, and Start. Note, however, that it is not normally possible to hold all four D-Pad buttons without specially modified controllers; standard NES/Famicom controllers will not work.

At the title screen, hold Left + B + Select and press Start.

When your score is good enough to make the high score table, enter your name as ''CAMERICA'' or ''MIG 29'' to see hidden messages at the high score screen, or enter your name as ''DIZZY'' to see a brief demo of The Fantastic Adventures of Dizzy.

At the Mission screen, hold Up + B + Select and press Start. The helicopter color will change, indicating that you are invincible, although your fuel still may run out. You should re-enter this cheat before the every mission as a result.

At the Mission screen, press one of the cheat sequences below, corresponding to the mission number, to skip to the next mission instantly.

At the high screen table, enter the following as your name for hidden messages. When the text listed here ends, fill in the rest of the name with periods; they all are 11 characters in length when filled in.

Hold the A button and press Start on the title screen.

Before the title screen appears (at the Codemasters logo, or after the game over screen, or after the demo loop is over), hold Right + A + Start.
