This information is outdated, but kept for nostalgia.

I've been asked to set up a tutorial of how to build a simple gc dol using the ogclib. You'll nead these files:

devkitcube-r0.zip ( http://heliscar.com/greg/gamecube.php )
libogc-2003-06-22.zip ( http://www.dextrose-forum.com/files/gc/source/libogc-2003-06-22.zip )
pong.zip ( http://www.dextrose-forum.com/files/gc/source/gc/pong.zip )

extract them to c:gc

devkitcube

libogc-2003-06-22

pong

We'll have to edit the pong main file. I usually use Ultraedit ( I find it superior to all other editors ) but any text editor will work. Open c:gcpongmain.c and uncomment these three lines:

#define COLOR_WHITE   0xFF80FF80
#define COLOR_BLUE    0x1DFF1D6B
#define COLOR_RED     0x4C554CFF

and add this

#define COLOR_BLACK   0x10801080

I don't add them to the video.h ( as suggested in the file ). You shouldn't edit librarie files.

We'll also have to change the path to the include files.

#include "..libogc-2003-06-22lib	ypes.h"
#include "..libogc-2003-06-22libvideo.h"
#include "..libogc-2003-06-22libmemory.h"
#include "..libogc-2003-06-22libpad.h"

change(79) vidInit (VID_MODE_640_480_PAL_60_YUV_16); to VIDEO_Init (VIDEO_640X480_PAL60_YUV16);
change(80) vidSetFrameBuffer((u32)fb); to VIDEO_SetFrameBuffer (VIDEO_FRAMEBUFFER_BOTH,(u32)fb);
change(98) vidWaitRetrace(); to VIDEO_WaitVSync();

Now all we have to do is compile it. In c:gcpong create a make.bat and run it.
