A QUICK but VERY IMPORTANT side note: when opening the user window you WILL have to resize it slightly horizontally and vertically EVERY time you start the debugger, to make sure that the picture tiles/sprites under the 3rd/re tab look correct. These is easy, but can be tedious and a little annoying to do, so make sure that if you open the screen to rip, that you rip a LOT at once.
The easiest way to figure out if the resize is right is to do this: when you look at the space with the sprite, you should be able to copy out this square canvas area and paste it into an image and have it be EXACTLY 128 x 128. Here is an example:
First the window:
Now the correct sized cutout part (make sure to NOT cut out the gray outline around the colored box with the sprite by accident):
Again......... this image should be exactly 128 x 128 if you sized the window right, which will ensure that the sprites are picture perfect and have no imperfections or artifacts.
