I was looking at the shiny sprites for some of the deltas and thought yanmegas was lackluster, the original shiny just has the non shiny colors swapped around so i decided to change it up.
The front and back sprite files have been named accordingly, place them into battlers folder and replace them. the character sprite sheet is named 829_1, you will rename it to 829s and place it in the characters folder, replace as well.
