First, you'll need a savegame from before you went to the port area to meet Ragetti and Pintel. If you have a savegame while you're in the tavern talking to Barbossa, that would be fine, otherwise you probably need one from before you go to Tortuga.
Edit "PROGRAM\console.c". Under a line which says 'int limit;' add this:
Code:
Locations[FindLocation("Tortuga_Port")].vcskip = true;
Load that savegame. Press F12 to activate "console.c". If you've added the line correctly, you should get a message on screen "Executed console". When you next go to Tortuga, it should be rather less busy, and you have a better chance of seeing both Ragetti and Pintel.
To cancel it, edit "console.c" again and replace that line with this:
Code:
DeleteAttribute(&Locations[FindLocation("Tortuga_port")],"vcskip");
Again, press F12 to activate it; again, you should get the message "Executed console". You may want to wait until the storyline has completed before doing that. I haven't played "Hoist the Colours" and don't know how it goes, but if you cancel the 'vcskip' and restore the normal crowd to Tortuga, you may have a similar problem if the story requires you to go to Tortuga again later.
