Yes, I have a diamond board. I just re-used the Black Star font that was already downloaded on the US Launcher on my 10th save slot with different colors. By "delete the font" are you saying that I delete the entire font?
I'm sorry. I rewatched the video for a second time. Your problem is a font programming issue. That is really hard to explain.
Please , check out some of the diamond saves I have made? They are all FREE. Linked is below in my signature bar. 00_diamond saves. That is what you should look through.
