	Nice work. Further, I realized tm20.avi is actually the same file as 
"Explode.avi" on the FF7 PC game. So it looks like you were working on 
the FF7 TM2 variation all along.

	Some of these files exhibit the chroma artifact quite clearly. It looks 
like compounded prediction error in the lower right corner.
