A while ago, I posted some hacks to change your pczapper frontend into what you would like.
With the new update 4.10, it's a little different, because the frontend is made up entirely of pictures, and no text.
For your hacking convenience, I made 2 templates in photoshop, one for the regular state of the buttons, and one of the hover state.
All you have to do is edit text and picture and put them in the program directory of the pc zapper.
