k i'm a little in a pickle right now, I have this strange problem with my game the upper part of my screen say 1/4 of the total screen is not rendered anymore.

I only have altered some code but even when i comment the whole sub out and no call to it is done i still get the upper part black. So now i am back to the part where I was before when everything worked perfectly but still got the problem :(:(:(:(:(:(

i feel powerless at the mmoment

does anybody has slightly an idea of what is going on? i use no scripting language, i use the png lib and the graphics.c for drawing

I was plagued by something like this for months, although my black section of screen was more like 10%, not the 25% you are describing, and there are a number of possible reasons for this. My black screen came and went as I added code to an expanding project.

For me I discovered (rather randomly) that if I don't clear the color buffer than my problems went away for good. I havn't seen the black screen in over a month now. I just changed things as below:

I had this issue for a few days and ended up using doublebuffering and a lot of
sceDisplayWaitVblankStart();

I think that's how I worked it out... :/
