Can anyone tell me whats wrong with this code? I have an interlaced 640x512
PAL display and the sprites are flickering, I thought it was my OT setup but
it seems fine compared to code that works from other stuff I have done. All
the sprites are properly initialised before hand etc...

/*-------------------CODE------------------*/

currentBuffer = GsGetActiveBuff(); // find out what the current frame buffer
is

while(PLAYING) // shell
{
 DealWithPad(1);

 GsSetWorkBase((PACKET *)packetArea[currentBuffer]);

 GsClearOt(0,0,&WorldOT[currentBuffer]);

 GsSortFastSprite(&titleSpr1,&WorldOT[currentBuffer],0);
 GsSortFastSprite(&titleSpr2,&WorldOT[currentBuffer],0);
 GsSortFastSprite(&titleSpr3,&WorldOT[currentBuffer],0);
 GsSortFastSprite(&titleSpr4,&WorldOT[currentBuffer],0);

 DrawSync(0);
 vsync = VSync(1);
 VSync(0);  // get the vertical sync interval

 GsSwapDispBuff();
 GsSortClear(0,0,0,&WorldOT[currentBuffer]);
 GsDrawOt(&WorldOT[currentBuffer]);

 currentBuffer = currentBuffer^1;
}

/*-------------------CODE------------------*/

If anyone can suggest anything that might be of use I'd be mighty pleased!

Thanks,
Max
