The easiest way to edit your ship and allot of other goodies if you don't know how to edit the files is to use the

IONCROSS Freelancer Server Operator mk.III.1 by JoeBoomz for Multiplayer games...

For Singleplayer games use the
IONCROSS Freelancer Character Editor mk.V by JoeBoomz

These two programs edit your saved game files...
For Multiplayer games you will have to be running your own server of coarse because the server keeps the saved characters files...
You can run a server on your computer by running the flserver.exe program that comes on the Freelancer disk and installs when you install Freelancer if you didn't already know that.
Then when you start a Multiplayer game click on LAN instead of Internet and your LAN will show up on the server list...Even if you only have one computer you can still do this...

Real easy. First get Freelancer SDK from the EOA forum below this one. Load that on your computer. Then open up your FL/DATA/SHIPS folder and find the file called shiparch.ini. Find this section:

hp_type = hp_turret_special_1, HpTurret01, HpTurret02, HpTurret03, HpTurret04, HpTurret05

See how that worked? You now have 5 turret hard points that can mount class 1-6 turrets. You can probably see for yourself how to adjust your shields and weapons. Good luck.

or.....yeah, if you want to save yourself time and trouble do what bakedpotato said.

Okey it works !!!
Thanx lot

I tried to add higher weapon class to the anibus "ids_name = 237041" but when I go into the game it's as if nothing was changed, I did what it says too... I added up from hp_type = hp_gun_special_6 to hp_type = hp_gun_special_10 same with the turrets, but no effect, is it possible to raise the class of the Anibus ship's weapons to 10? thanks!

Did you actually try to mount said weapons on the ship? If you made the changes outlined here, the ship will be changed, but the infocard will still say "Max Weapon Class: 6". You'll just have to remember that it's not true.

sorry, but i really don't get what u all typed there, i can't find a thing either, i downloaded the Single player typ, and now iam stuck, because, the only thing i want to make is that i can buy a Transport ship , but it's too complicated!!

I have changed the Anubis so it has stats:

Gun\Turret = 8\3
Opt. Weapon Class = 8
Max. Weapon Class = 10
Add. equip = M\CM\3xTorpedo/Disruptor
Max Shield Class = 10
Cargo Space = 160
Armor = 14300

I now want to change the generator, because the old one doesn´t have enough Energy to fire longer than 4 Seconds.
Do you know, where the generator is Set?

misc_equip.ini contains the information about the power plant used by the ships

Oh and... btw... as soon as I've gotten the Custom Weapons tut. done (and Harrier has told me that it works correctly and is understandable)... I think I'm going to take a shot at showing people how to build new ship mods using XML and FLMM... I have studied Mephistopheles's code for the Promethius mod (which was very slick, Meph., and I'll thank you for giving me something to borrow from) and made some very serious progress towards implementing a new ship with custom Infocards very, very easy (which is good, because the "old-skool" way was driving me nuts lol).
