I'm using "2020-04-01bRagexe" and yes I'm using the load custom lua file but I put the correct name when I'm building the exe with nemo. The itemInfo that I used I downloaded from the branch master git "ROenglishRE" and I put this path to the load custom lua -> System/itemInfo_EN.lua. I don't know what I'm doing wrong.
On the other hand, I fixed it the icons, thanks so much.
EDIT: Finally I can resolved it. Thanks so much for your patiens!
I have another question, maybe is pretty silly, How I know in wich ragnarok version am I? I means, in what chapter 13.3, 15.2 (I don't know how is it going)
