Hey, Just managed to get it work!   I had some of the issues others had because the .diff was old. After manually editing few lines, it worked for me.   These days you could just use/make the costume items in the item_db. Just like normal headgear except equipment's placement is different.    1024 = Costume Top Headgear  2048 = Costume Mid Headgear  4096 = Costume Low Headgear   But its nice functions for making just a quick costume change.   My commits at GitHub:  * https://github
