Gack!
Ok, I'm the guy who made the hand patch. Yes it uses the hands from the higher-res Cloud field model. The two "higher-rez" (really just more realistically proportioned) models in question are:
clgd.hrc //Cloud
animations used by the game:
aaff.a
cmda.a
cmdb.a
cmdc.a
cmdd.a
cmde.hrc //Jessie's upper torso, minus forearms+hands
animations used by the game:
cmhb.a
cmhc.a
cmhd.a
cmhe.a
halkun is correct. Both *do* appear in the game, in one scene: rootmap (the scene where Jessie shows Cloud the map of the subway system.)

There. If anyone wants a 50MB HTML presentation explaining all this, let me know. Any other questions?
