Well, here's the first beta. It contains NPCs, Yoshis, and Effects. Credits included in the file. I had some issues because of time limits.
Known Bugs:
Larry's effect is not recolored
Some Goomba effects are placeholders
NPCs that look like blocks (airship NPCs etc.), door effects, and block effects have been left for HenryRichard in a folder
