ok, this' how i did it.
1) download the
Gentlemen_of_Steelport_v1.0_Beta_3.rar file from
http://idolninja.com/sr2.php
2) (i use WinRAR) right click the rar file, choose "extract to Gentlemen_of_Steelport_v1.0_Beta_3"
3) open the newly extracted Gentlemen_of_Steelport_v1.0_Beta_3 file, if you have other mods (e.g. nude mod), u may put them in the subfile of
optional_mod_stuff,
1-MY_EXTRA_MODS. (i've heard some mod can't be installed in via GoS so you gotta check that out)
4) go back to Gentlemen_of_Steelport_v1.0_Beta_3 main file, you should see
Create_Custom_GoS_v1.bat, open that.
5) if you want basic stuff, enter C, otherwise A
6) after u enter A, u shd see a list, make sure NOT to tick
3.1 Extended Character Creation Sliders, leave that empty! (if u don't want character to look deformed)
also, some weapons mod doesn't work with gang one mod.
7) after picking all ur desired mod, i press P, then wait few seconds for the files to be created.
8) in Gentlemen_of_Steelport_v1.0_Beta_3 main folder, u should see a subfold named
MY_CUSTOM_SR3_MODS, copy everything inside MY_CUSTOM_SR3_MODS,
paste it to C:\Program Files (x86)\steam\steamapps\common\saints row the third\packfiles\pc\cache\
(game folder maybe slightly different on your pc)
9) should be working if u start the game now.
