$1E9CD = A9008D00A0
$1E631 = 20C4FF
$1FFEF = 8D0203A9018D00A060

hmm, get an odd sprite glitch with link when defeating a boss... right below the in-game map, is a green line, and part of links hat is messed up?

UPDATE 7-16-13

Now works on an actual NES!

$1FFA5 = 4CCDFF
$1FFDD = A2058E0080BD8AFF8D0180CA10F44C40E4
$1FF9A = 000204050607

Locate all the 4C40E4's and replace with 4CCDFF
