Sprite Wrapping Glitch
From SnesLab
								
												
				The Sprite Wrapping Glitch appears to be a PPU design flaw that can occur under two conditions, according to fullsnes:
- In 224-Line Mode, when a sprite with a height of 64 pixels is located near the lower screen border
 - In 239-Line Mode, when a sprite with a height of 32 pixels is located near the lower screen border
 
The sprite can reappear at the upper screen border.
