That is correct, and it's in my table too.
You just misinterpreted what I wrote earlier, since I didn't word it very well. Killing Pirates is great if you want to be friends with Bounty Hunters, Confed, Militia, and Merchants...but not if you want to be friends with everyone including the Pirates.
One thing I used to wonder was what happens if you kill some Pirates and some Bounty Hunters/Confed/Militia/Merchants and balance it out. And according to my table doing that will eventually make them all your enemy so it doesn't work.
The only way to befriend everyone it seems is to kill many Retros.
If you want to see what friendly Retros say, just edit your savegame file. From DOS type "debug XXXX.sav" and type d <enter> and on the right there will be some words PLAYSCOR. Uh, well it's hard to explain nevermind. Hopefully you already know how to do this.
Anyway just fill all the fields sort of after PLAYSCOR with 00 40 00 40 00 40...hard to explain and you have to know exactly where to start and stop. Oh well.
Anyway the only thing you can say to the Retros is This Attitude Not Possible and all they say back is This Attitude Not Possible. The Steltek Drone is the same, except it won't reply at all. Some Retros are different, and you can tell them "Free all Pot Prisoners" but they never reply with anything. The Steltek Scout, if friendly and not in the storyline mission (you need to cheat to bring him out...for me he is my wingman) will always say This Needs To Be Written, and you message him with This Needs To Be Written. Haha. But I edited my OBJECTS.TRE file so the Retros and Scout say whatever I want.
Other things I've done with my Privateer game are edit the SPACE.TRE file so that I am the new ruler of System DN-N1912. My Centurion lives on their Pleasure Planet, except that while in space it looks like a Steltek Derelict Base. And the whole system is populated by armies of Steltek Drones and Scouts, usually 8 total ships at each navpoint. Contrary to a internet textfile I downloaded from CIC, you can put as many ships as you want at an navpoint. The only thing is that the game will crash if the action gets too intense. If buff ships with many guns and missiles are going to be fighting at a navpoint, try not to put more than 8 ships there. If everyone is going to be friendly with each other, and you don't plan on starting a fight with them yourself you can afford to put probably 20 ships at a navpoint hehe.
