Star Trek: Insurrection ship:
Import the "temp.cxt" file in the "ship main" folder in the game folder to get the ship from Star Trek: Insurrection. Do not decommission the ship or you will lose all of the credits you have. Note: This will not put any errors on the system. You can also use this as a lose money cheat. If you do not want the ship, remove the cheapest part of the ship and you will get a lot of credts.

Unlimited credits:
Create a new ship using as much credits as possible. Use the "Export Ship" option after building has been completed. Return to the main menu and restart the game using a new Admiral name. Return to the fleet screen and use the "Import Ship" option to retrieve the newly created ship. Decommission the ship after it is added to the fleet to gain its value in credits. Repeat this process to accumulate an unlimited number of credits.
