Srsly... I still have no clue.
I'm going to go ahead and assume anyway.
If you are referring to skin codes. You take the text for the skin code, and you paste it in the Custom Save Data text box, and then click Load.
If you are talking about literally writing text on a girl's body, that's completely different and I can't help you.
Also, I don't know why you linked to my archive.... but since you did that... Download the 1.9.1b.exe and try that.
