If debug mode isn't enough, here's a few more command-line options.

Code         Effect
POWERBALL    Debug mode (see above)
TICS         Display TIC INFO in score area
MUSIC        Enable music test mode. Press Backspace followed
             by any arrow key to change music.
RADAR        Displays radar.

Please note: This only works on full version.

While playing, type "JAM" then hit ENTER. You will gain full life, ammo, access cards, and all guns but your score will drop to 0. Here are some more codes to help you out. <6>+<7> - Collect all bonus items (gold, ammo, health, etc...) <7>+<8> - Kill all actors. <6>+<8> - Collect all bonus items AND kill all actors.

To access debug mode, start the game with the command "bstone powerball". When the Jam logo appears, press and hold Left Shift, then press and hold Right Shift. If you did this right, a sound will chime.
