First you need the paintbrush application (it`s called "paint" if you have a p.c.)
p.s. my computer is not saving the image tags that's why There is none
Step 1: Find a Good Image
Mario images are good to start with because they are 8-bit.
the controls for "paintbrush" are pretty simple .
the mouse moves the curser
the percentage at the bottom of the window is how far you are zoomed in.
you change the color to almost any color with the tool bar.
Step 2: Finish and Save
finish your image AND SAVE IT the first time I thought it would auto save and it did not so it was gone for ever :(
