Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. With a text editor, edit the "Ships_init.c" file in the "/pirates of the caribbean/program/ships/" folder. Locate the following line under each individual ship type:
refShip.Price =19000;
Change the "19000" to "100" and your ship will now cost $100. This can be changed on any ship of your choice.
