Sprite Assembly

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

Skelleton:

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

 20af4   04 fd 09 06 28  ed 09 04 28  f8 f9 02 28  f5 e9 00 28  03  f8 09 0c 28 f7  f9 0a 28  f5 e9 08 28
         ss aa bb cc dd  aa bb cc dd  aa bb cc dd  aa bb cc dd  ss  aa bb cc dd aa  bb cc dd  aa bb cc dd

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

 First byte: 
 2=Normal  
 6-7=Mirror 
 A-B=Flip 
 E-F=MirrorFlip  
 BadNumbers=0 1 3 4 8 c d 

 Second byte
 0=Pal 0
 2=Pal 1
 4=Pal 2
 6=Pal 3
 8=Pal 4
 a=Pal 5
