Ok, here's a tutorial on setting up the female romance (going to be a long post, so get some coffee :rolleyes: )
  All files should be created with an ASCII text editor like Notepad in your override folder or some where that you can find it, for example in a folder called Kotor Work. Don't include the quotes. 
 Create a text file called "k_con_flirt.nss"  
 Put the following lines in it: 
 //:: k_con_flirt
 /*
 checks to see if npc and pc are of the opposite sex and the pc's
 charisma is normal or better
 */
 //:: Created By: Jason Booth
 //:: Copyright (c) 2002 Bioware Corp. 
 #include "k_inc_debug" 
 int StartingConditional()
 {
 if(GetAbilityScore(GetPCSpeaker(),ABILITY_CHARISMA ) >= 10)
 {
 return TRUE;
 }
 return FALSE;
 }  
 Next create another text file called "k_con_flirtno.nss" 
 Put the following lines in it: 
 //:: k_con_flirtno
 /*
 checks if pc charisma is low or pc and npc are same sex
 */
 //:: Created By: Jason Booth
 //:: Copyright (c) 2002 Bioware Corp. 
 #include "k_inc_debug" 
 int StartingConditional()
 {
 if(GetAbilityScore(GetPCSpeaker(),ABILITY_CHARISMA ) < 10)
 {
 return TRUE;
 }
 return FALSE;
 }  
 Next create a text file called "k_con_isfemale.nss" (if looking for male relationships use this as your base, I believe the male version is "k_con_ismale.nss", but don't quote me) 
 Put the following lines in it: 
 //:: k_con_isfemale
 /*
 checks to see if pc is female
 */
 //:: Created By: Jason Booth
 //:: Copyright (c) 2002 Bioware Corp. 
 #include "k_inc_debug" 
 int StartingConditional()
 {
 return TRUE;
 }  
 The last text file is "k_hjuh_p17.nss" 
 Put the following lines in it: 
 void main()
 {
 SetGlobalBoolean("T_JUHANIROM", TRUE);
 }  
 Finally, download a compiler such as the one here

 Compile and enjoy.
