Hi all,

First, I want to say that I have already read about this problem in the forum. I tried to fix it but with no success.

What I'm trying to do is the lesson11 of pspgu of PSP-PROGRAMMING about display list. I think my app freeze when I try to do sceGumUpdateMatrix because when I comment it, the app run but don't display my polygons. Maybe something is wrong in the BuildLists function but I'm familiar with list in openGL and all seems ok. Please take a look at the source code and give me a feedback, It will be appreciated.

Code:

//   Includes
#include "main.h"

#include <malloc.h>
#include <pspdisplay.h>
#include <pspdebug.h>

#include <pspgu.h>
#include <pspgum.h>
#include <pspctrl.h>
#include "CTimer.h"
#include "TGALoader.h"

//   PSP info

Don't really have the time to read/understand/fix the whole listing...just find a serial cable, connect PSP to PC, open a terminal on PC side and insert pspDebugSioPrint into code every now and then. So, run your program and see from terminal WHEN your app stops working. It could be a good starting point, indeed. However 95% of freezes comes from writing into memory at the wrong address.

Give yourself a bigger display list to work with...

Code:
dList    = malloc( 1536 );


Is tiny.

Remove all the FPS stuff completely from your code. I've had others come to me with problems because of it.
