DS Vania Rip Project

[Paddy]

That kind of begs the question...if it's so easy, then why doesn't a spriter do it?

However, the Shanoa sheet is the opposite extreme end of the spectrum - it would take hours, if not days to compile all of those fragmented sprites into every solid frame of an animation.

That's the reason. It takes more free time than most people have.
Besides I still don't see why only a spriter could do this. Get a ROM and load it up or look at youtube videos of Shanoa and then see what pieces correspond to what animation.
You also seem to forget that this project is still WIP and not even close to being complete. If you really want these sprites you will either take the time to assemble them or be patient and wait for someone else to do so.

If you plan to assemble them, they are grouped in 128x128 blocks.
