<= R0 = pointer to ROM sprites area
R1 = pointer to RMA sprites area
This SWI gives you the two areas that make up the Wimp sprite pool. Note that the RMA area may move around (when sprites are added) and that Window Managers >= 3.5 actually use a dynamic area instead of the RMA.
You can use these addresses with OS_SpriteOp, but you should always use Wimp_SpriteOp.
The only real use for this SWI is for saving the ROM sprites to a file:
SYS "Wimp_BaseOfSprites" TO ROMBase%,RMABase%
SYS "OS_SpriteOp",256+12,ROMBase%,"filename"
See PRM 3, page 203.
