Files Required:
-Decomp
-Earthbound ROM
-Tile Layer Pro
-NotePad

Once you have all of these files (1st and 3rd files at pkhack.starmen.net), get a position where you want to see the graphic. In this tutorial, we will be using EDF5D, the location of the sound stone screen graphics. The filename of the ROM in this tutorial will be earthbound.smc

Open up NotePad and type in: decomp.exe earthbound.smc EDF5D bob.smc

decomp.exe - This is the decomp program.
earthbound.smc - This is the ROM to get the graphic from.
EDF5D - The position in the ROM to get the graphic from. (Sound Stone screen graphics in this tutorial.)
bob.smc - This is the output file that the graphic will go into. Decomp will create this file automatically.

Now that you have all of that in, save the file as a .bat file. We will use JeffMan.bat in this tutorial.
Now, just run the .bat file. A black screen should pop up for a second or less. This is normal.
Now, open up Tile Layer Pro and open up bob.smc with it. You should see the graphic in there.

Well, that's about it!
