The Sprite assembly contain more or less two tables. One that will point to the Frame and one that will draw the Sprite in 2x2 squares. This is the most used format in SC4. The assembly number in the event table is almost the same as the pointer. The routine does increase or decrease it a bit for some reason so they do not perfectly match and are a bit harder to find.

Format Example with Skeleton

 b2f1       f48a 058b 
 	    bbbb cccc	
 bbbb=Frame1 
 cccc=Frame2

ss=Size Number of 2x2 queuers to use. 00 Is not a number and will overload. A new ss means a new frame in the example above are two frames shown

aa=Offset (01 move one pixel right 80 will wrap)

bb=Offset (01 move one pixel down 80 will wrap)

cc=Tile Pick Tile Square 2x2 ..

dd=Orientation and Palettes

In most cases the hitbox is writen (STA) as the event get loaded. So it is easy to find with a breakpoints.
