This is a disassembly of sprite 64 in SMW, the line-guided rope. The extra bit determines whether the rope will be short or long, but unless you use the No Sprite Tile Limits patch, it will always be short.
now SA-1 hybrid.
Support for LM3 exlevel settings. Only works with pixi 1.2.4+
Does not work with the Line Guided Acts Like Fix patch. But since the heart of the matter is the sprite working by being inserted without the user having to insert the patch, that's enough to me to warrant an approval.
