• [J] [A] [M] [Enter] - These keys are to be pressed one at a time. When all are pressed, the message "Now you're Jammin'" appears, and you will be given all keys, and you will get 100% health. Your score will also be taken to 0. This will only work on the registered version of the game.

• POWERBALL - Enables debug keys. This also requires that you hold down the left and right shift keys during the JAM Logo intro. Don't hold them down until the white letters start to appear. Once the PC-13 screen is loaded, you can let go. You will hear a "ching" sound during the intro when debug mode has been successfully enabled. The "ching" sound will only happen if you have a sound card. If you have a PC speaker, you won't hear this.
• TICS - Display TIC INFO in score area.
• MUSIC - Enable music test mode: [backspace] [arrows] changes music.
• RADAR - Displays a rotating overhead view during gameplay. Please note that this REALLY slows the game down, to the point of being unplayable.

  These cheat keys can be use during gameplay only if you invoked the program with the "powerball" parameter:
