I'll assume from the thanks that it's sweet 
Also by the way, I'm currently trying to merge the hammers and hammer-swinging sprites. I've managed to whip up some code to automate this almost perfectly, but there's a slight snag with some of the sprites.
You know how both the swinging and hammer sprites are in a grid? Well, from what I can tell, some of the hammers in the second column are lower than they should be. In this case they seem to be exact duplicates (in both appearance and position) of the hammer in the same row that's in the first column. There's also one hammer in the third column that matches both the first and second column's hammers in one row.
The rows in which this happen are rows 2, 3, 5, 7, and 9. It also happens in most of the rows below 9 (the ones with only 2 columns) but that looks correct.
Most of these I can fix by hand and luckily all other hammers seem to be in the right place. My only problem is that the row in which column 3 also has an identical sprite, row 5, is the row that has Mario facing the screen and these 3 columns are of course the frame in which he has the hammer behind him. The main problem here is that since most of the hammer is obscured I can't clearly see where it's supposed to be positioned (other frames have bit of Mario taken out where the hammer should be, so it's easy to see).
What I'll do is see if I can get some screenshots of him whacking the hammer in-game, and I can see where the edges of the hammer are in these frames. Hopefully I can then use that to find the position the hammer should be in.
TL;DR I've got a problem and I'm going to try and fix it. Basically I just felt like writing it down, I'm not expecting anyone to really have a solution or something, I don't even know if what I wrote makes sense. If Greiga Master is reading this he might want to check that he ripped the hammer sprites correctly, if he did then that's fine and the game just stores and uses these sprites weirdly.
EDIT: Tried out my idea and it worked, so I'll just arrange these few frames by hand. Sorry for the wall of text post
