Extras:
Note: This trick requires the Dreamcast Web Browser. Load the web browser and enter
the Sega's Dreamcast Network site. Enter the Games/Downloads/Game Extras area.
Download the "Dynamite Cop Detonator Pack" on a VMU that contains a saved file from
the game. Start the game CD and enter the option menu. Select the "Detonator Pack"
and choose to combine the Detonator Pack with your existing saved game file. The
following extras will now be unlocked. A bonus stun gun weapon will appear randomly
during the game. Extra graphics will appear in Caribbean Pirates mode. Highlight Ivy
at the character selection screen, then hold Start. Cindy from Die Hard Arcade will
be unlocked.
Arresting enemies:
You cannot arrest someone important such as the big "crab" guys or a baker. The
only people that can be arrested are most of the regular people. In order to arrest
a person, you must have a pistol (and not a machine gun). The person must be
weaponless. Get behind them and press X. That should make the cop say "Freeze".
Immediately press X again to avoid getting kicked. If done correctly the person
should be crawling on their knees with their hands behind their backs.
