"Nutty quip goes here!"

=> R0 = reason code

This SWI controls the sprite system. R1 and R2 are often used to select a sprite. When they are, the following applies :

R0 bits
8 & 9 R1 R2

00 (+  0)                          sprite name
01 (+256)     sprite area     sprite name
10 (+512)     sprite area     sprite ptr

In the first case, the system sprite area is used. Do not use this.

This SWI is indirected via SpriteV.

See PRM 1, page 761.
