Is there any way to batch extract NCGR (DS Graphics) to PNG?

I thought about making a batch conversion for these formats once before, but I don't exactly remember the problem I encountered.
I think it was something to do with NCGR being a cell format. You would need the map file (NSCR) or (NANR) to build the sprites from the cells.

Of course, background stuff probably wouldn't need it, but it's the inconstancy that caused problems and makes the whole process not worth it.

Basically, tinke is probably the best way to rip these kinds of graphics.
