I wanted every portrait to have Toriyama's artwork inside of it. Unfortunately because of the Shenron's being from the latter part of GT, I could not find any concept art or sketches from Toriyama. And because I couldn't resist Yamcha's portrait is...from the anime :) If you do not want the background artwork of Goku passing by installed just delete the sprite folder within the UI folder before installing. Also SSJ4 Goku has a portrait by Toriyama so the title is incorrect.

Place in your data folder. Specifically place the CHARA01.emb in data>ui>texture and the CMNBG.emb in your data>ui>sprite
