Hey Hey, maybe a short explaination would be good.
For the Weapon you have to do: Data -> Item -> Weapon -> there you put the PS_S20_27.pg file and overwrite it(make sure you saved the filme before) well than you go into the Folder "Tex" and there you copy in the file PS_s20_27.png and overwrite it if needet, make sure you did a copy from the original.
So now we come to the Armor ^^
Data -> Model -> Clothes -> Tex -> copy the files which end with "gtx" in this folder an overwrite it, like before make sure you have a copy.
Voilá we got a nice Red Armor and Sword 2Hand.
The Armor is G105 Upgradet and the Sword is G100 2H Imperial.
