== Step 1 ==

Open the image you want to be displayed on the GB in the GIMP. 
[[Image:burger1.png]] 

Now we need to make this image an 8 bit pcx file. 
[[Image:burger2.png]] 

Go to Image -> Mode -> Indexed and change the max number of colors to 8. 
[[Image:burger3.png]] 

Resize the image to fit the GB's screen size. 
[[Image:burger4.png]] 

Save the image as a pcx file. 
[[Image:burger5.png]] 

== Step 2 ==

Now use this command with the image you saved in the same folder as pcx2gb: 

<pre> pcx2gb n d *imagenameyousaved*.pcx *tilesfilename*.c *mapfilename*.map</pre>

Press enter a few times and your tiles and map files will be generated. 

== Step 3 ==

Now create your file to actually display the image on the GB.

<pre>
#include <gb/gb.h>

#include "tiles.c"
#include "map.map"

void main()
{
// Load up the tile data
set_bkg_data(0,255,tiledata);

// Switch to VRAM
VBK_REG = 1;

// Switch out of VRAM
VBK_REG = 0;

// Set screen x,y pos to 0,0 and draw the map 20,18(size of the screen)
set_bkg_tiles(0,0,20,18,tilemap);

// Show the background
SHOW_BKG;

// Turn the display on
DISPLAY_ON;
}
</pre>

== Compile and done ==

After compiling and running my output looked like: 
[[Image:Gbburger.PNG]]

 Note: the screen may "glitch" up a few times and then turn black. This is normal. If you're stuck in the window, then CTRL+Tab out to return back. Also, the filename may need to be limited to 6 characters and not use hyphens. If the program doesn't work it's possible that the image was not in proper 4 color mode, but PCX2GB will not warn you of this.
