Change RK sprite

Due to my friends request, I'll tell how to change the RK sprite to the new RK sprite. Please read carefully the instructions on this post as the process is little complicated.

Things you need:
-new RK sprite (download)
-GRF Builder (download)
-Knowledge and Patience

Step 1:
Back up your data.grf (to ensure safety incase bad things happened)

Step 2: 
Make the following directory:
"new RK\data\sprite\인간족\몸통\남\" (this is for male sprites)
"new RK\data\sprite\인간족\몸통\여\" (this is for female sprites)

Step 3:
Paste
룬나이트_남.act
룬나이트_남.spr (this is for male rk)
룬나이트쁘띠_남.act
룬나이트쁘띠_남.spr (this is for male rk w/ peco)
to "new RK\data\sprite\인간족\몸통\남\"

Paste
룬나이트_여.act
룬나이트_여.spr (this is for female rk)
룬나이트쁘띠_여.act
룬나이트쁘띠_여.spr (this is for female rk w/ peco)
to "new RK\data\sprite\인간족\몸통\여\"

Step 4:

Open GRFBuilder, Click Open and choose f3data.grf (You can choose what server you're playing. data.grf for New Chaos, fdata.grf for Valkyrie, f2data.grf for Valhalla, and f3data.grf for New Loki).

Click Merge Dir and choose data folder inside the newRK folder you created while ago.

Step 5:
Repack, Ok, ok.. then close.

Note:

If it didn't work, repeat all steps or restore the backup if you give up trying.
