Fourth cheat:Unlimited crew

This cheat will allow you to have as much crew as you wish, but will not provide you with immortality. Although you'll have as much crew as you like during trade and travel, it will return to the max number of crew-members+1 during fights. That's the reason why crew quarters are needed in your ship modules.

Since this cheat doesn't provide you with immortality, what does it provide you with? Well, it allows you as much crew as you want for trading with Druuge but, more importantly, it gives you ability to evacuate from fight and replenish your fighter's health. Here's how to accomplish that:

1) Go to base. Menu Shipyard.
2) Insert current number of crew members into Cheat Engine (it works only for your main ship, so input that number) and search for it with First/New scan.
3)Buy or sell one crewman (or crew-woman). Search for new number with Next scan.
4) Repeat step 3) until you get single address (it will probably be green)
5)Double click on it until it goes to lower portion of Cheat Engine window.\
6) Insert new number of crew-members. You'll notice that it changes when you buy or sell another crewman (probably sell).

I don't advise freezing this address, since it's system address and changes during game processes (specifically, fight :( ) so you have great probability that game will crash.

Good luck and have fun.
