Shine's tool extracts the game save so you can load it into a hex editor. you play the game and progress a little, like win one race. you save your game and use the tool again but this time you compare with the previous save to see what change. you will come up with about 7 diffrent changes. you can make an educated guess and edit one of the changes. once you edit it you need to upload it again using Shine's tool so it can encrypt the save again. its a little like trainer making. once/if the image loader comes out for the games you will be able to load a ram dump utility and make real trainers.
