Ok so if you've read the FAQ then you've confirmed that:
   o Your GsSPRITEs are set up correctly. Check it AGAIN, one little mistake and you see zilch
   o The sprite image is in VRAM (confirmed with MoveImage)
   o Your OT's are set up correctly
   o You're setting your packet base every frame.
   o Your X/Y coordinates are sensible.
   o Your Sprite RGB values aren't 0.

Here's a very basic loop for drawing a sprite (after initialisation) - are you missing any of these
calls out? (This is off the top of my head, apologies if _I've_ missed anything out or the params
are incomplete).

while(1) {
	buff = GsActiveBuffer();
	GsSetWorkBase(PacketArea[buff]);
	GsClearOT(&OrderingTable[buff]);
	GsSortSprite(&MySprite,&OrderingTable[buff],0);
	DrawSync(0);
	VSync(0);
	GsSwapDispBuff();
	GsSortClear(&OrderingTable[buff],0,0,0);
	GsDrawOT(&OrderingTable[buff]);
}

Cheers,

James
