I've been fiddling with the looks of the zapper, with this as result:
Kinda nice, if you like purple.
It's as I suggested in the last post: just overwrite the images with the new ones (perhaps backup the old ones) and voila.
For those with a desire for purple,
here's the rarfile that contains the images. Extract in pczapper/program.
It includes the .psd files with the buttons, so you can change the text of the buttons.
If you use photoshop, you can use a marquee (selection), then crop each button and save it as png.
Then undo the cropping and move the marquee to the next button.
Happy hacking!
