The mod I created doesn't show up in the list in the main menu. I must have done something wrong or missed a critical step.
Did you try to create the mod using the editor or did you try to create a pak file manually using Norbyte's tool?
I tried creating the pak file manually. I did look at the editor first, but I couldn't figure out how to use it to do what I wanted. I could try looking at a copy of the "Free Pet Pal" mod in the editor and seeing if I can figure out how it works in there.
