Freedom Force

Freedom Force is a light gun game that is played with the Nintendo Zapper.

Level skip
Pause the game (first controller must be connected), then press the A button 16 times and one more time for each level. For example, you must press the A button 16 + 1 times for first level, and 16 + 5 times for fifth level. This works only for the first five levels. Upon completing all 5 levels and beginning the game from the start with a higher difficulty level, this option will be unavailable.

Sound test
Connect a second controller to the console instead of the Zapper. At the game mode selection screen, on the second controller, hold Up + Left + A + B. Use the second controller to select and play a track. Press A + B to exit the sound test.

Secret message
After beating all 5 levels, when "CONGRATULATION" appears on the screen, press A on the second controller. "HIRO-KUN" will appear on the screen, which is the nickname of Hiroaki Higashiya, one of Sunsoft's programmers. This nickname also appears as a secret code in Platoon.

VS left-overs
There are a couple of left-overs from the arcade version of this game for VS. Unisystem by Nintendo. To re-enable them, use the Game Genie code. This will enable:
 * The title screen will have "INSERT COIN" instead of "AIM FIRE TO..."
 * Showing and using hi-score table. You can write down your initials when beat any of the hi-score records.
 * So sad, hi-score screens are quite unfinished, and your initials just isn't saved at all even if entered.
 * Hi-score table itself is quite different form the final one (featuring "ASS"), used in the Arcade version:

Unused text
There are some unused text strings in bank 1. There is no cross-refs to these strings in code at all. It was probably meant to be shown somewhere in attract mode. SUN ELECTRONISC CORPORATION WELCOME TO OUR OFFICE MR RICHARD MR MENDHEIM Another one unused string present between generic game strings at bank 3. PRESENTED BY [SUNSOFT] Note, that "[SUNSOFT]" written with another font, which is mostly removed from the final CHR ROM data. There is only [-FT] left.

Unused cutscene animations
The game contains 4 more animation frames to the final part of the starting cutscene. A man standing at the helicopter crash site with injured pilot was meant to finish pilot with a gun. Obviously, this scene was removed from the final game because of Nintendo of America's censorship policies.
