well i guess no one knows how to do that
well after some thinking and checking how the terra empire mod adds new factions (which i beta test) i found the answer and have the "nomads" and "the order" in my rep screen
now for the mission part

it would be great if you could post your results here. I will encounter the same problem in my mod but had no time yet to investigate it. I remember i saw something which seemed to hold the answer but i forgot where. So please enlighten me

well what i did was because i had the nasty feeling DA hardcore locked the group names so they would not show in the rep screen nor would get any missions
I managed to make the order have anumises to patrol around their bases first
then i did this to make them show in the re screen, missions don't work yet , don't know why

I renamed the fc_or_grp and fc_n_grp in all files i could find them in
basicly i renamed fc_or_grp into fc_ord_grp and fc_n_grp into fc_nom_grp, but u can take any name u like ofcourse

List of files to edit (just use "replace all" function in your editor after decompressing them):
/DATA/MISSIONS
faction_prop.ini
empathy.ini
mbases.ini
/DATA/RANDOM MISSIONS
vignette_parms.ini
rmlootinfo.ini
killablesolars.ini
/DATA ROOT
initialworld.ini
/DATA/EQUIPMENT
commodies_per_faction.ini
/DATA/AUDIO
voices_base_male.ini
voices_base_female.ini
/EXE
mpnewcharacter.fl

the whole thing took me about 10 minutes or so
but be adviced i don't give about singleplayer, since i only play SP original , so i just deactivate the mod then.
If u want to make this work in SP so the game stays intact u have to add new sections to every file where u copy parts of the original section showing the group and then rename the group , so u basicly have the original fc_or_grp and a copy of that block/section with fc_ord_grp in it (a lot lot lot extra work hehe)
And the game will prolly still stay the same since u added a new house that isn't used by the gamestory

This since the SP scrips might still refer to fc_or_grp , which i renamed and don't exist anymore , lol

I think you're right. I had a look into common.dll ..there are the follwoing factions mentioned:

fc_uk_grp fc_ouk_grp fc_q_grp fc_f_grp fc_or_grp fc_n_grp fc_rn_grp
fc_kn_grp fc_ln_grp

i can't check what the programm does to them (no decompiler atm) but they are the only factions mentioned in the exe's so there is something special to them...thx for your help! I will not use these faction nicknames in my mod.

your welcome
i made the missions work for the order now and added the slave 1 to the infocards.dll so i don't have to hassle with seperate dll files
just wish there were more ships like that that would fit into the game
the slave 1 is kind of freelancer lookalike
the rest of the SW ships would look kind of alien in the game hehe
anyway my modding abillity is aproving , few weeks ago i knew nothing about it
thanks to shsan and his awesome every day improving 2d system editor and some logical thinking i came a long way in figuring out how things work
now to make the nomads in the missions hehe
