Skins are very easy to add.

Create a folder within the main skins folder.

Put pictures in folder.

Pictures must be .jpg
Size does not matter (the shacc will resize to fit.) but a balance should be made between size and detail ie. the smaller the pic the less detail.

If the folder contains a pic called all.jpg then all skins will be this pic otherwise the folder must contain one of each below.

Main.jpg (for the main shacc screen)
multi.jpg
sims.jpg
console.jpg
hand.jpg
comp.jpg
singl.jpg
setup.jpg
back.jpg (for the background where the screen shots etc. are)

Add folder name to skins\skins.txt
