I based a few moves off of X68000 and a few off of CV4.
However, the moves are for reference only and no frames were directly copied from other games' frames (though they are quite similar but my Simon is smaller than CV4 Simon and doesn't have the weird walk that Chronicles Simon has).
I'm particularly proud that I did a full spritesheet for Simon.
BTW, MetroidQuest does not use the full spriteset either as his game came out before my sprites were done and he started posting before I started. In fact, I think the reason I made the spritesheet was because people were complaining to him that using a Red Richter was a cheap cop-out.
Here are all of the frames (from the Spritework thread):
