I get the same on modern hardware (my Iyonix died a while ago now).

I am a little confused. The PRM says that R2 is a ptr to sprite name,
and also says sprites are always accessed by name.

Looking at the analogous OS_SpriteOp 12, it does say R2 is pointer to
pathname, so that should be ok.

I cannot get this call to work on ARMX6 hardware - the "Sprite
doesn't exist" error is raised.
