The Official M&L3 Ripping Project *WARNING CONTAINS SPOILERS*

[Greiga Master]

Holy moly, these are wonderful! I'll wait until you've figured out the alpha problem before I try and sheet them, but seriously this is better than I could have hoped for. I mean, it even has half of the bros' knocked out sprites without the other carrying them (which will probably be a challenge to assemble but hey).
They are missing shadows though. You said you wanted to keep shadows for animation purposes, right Ridge?

The issue with the shadow is that it isn't exactly part of the sprite, It's in FObj and separate from the mario sprites for example, although I guess if someone went through a lot of trouble they could add them back on. The alpha channel issue doesn't exactly effect any of the current sprites there are just some I couldn't get without having support for that format and were skipped.
