ok...my map is 500mb, never seen him. ever.
all i do is explore, and if he's not in that 500mb of blocks, i highly doubt he's in the game.
my map is so big, when a friend makes a map, i just zoom around till i find the same spot on my server.
theres no image, encoded image, skin link or hidden files in any of the minecraft files that link to anything like the supposed "herobrine" exept the default skin.
theres also no code that changes the eye-color pixels to the color that there ment to be. (checked, decompiled, dissasembled, reverse enginered, and recompiled to find hidden code) also, on a side note, notch's char is coded to have a cape....lol
