Not sure I follow you, but if you mean the original black/white contest map, i just did an image size change in PS to increase the size to 2400 x 2400 pixels, keeping the resampling to "nearest neighbor" to make sure there would not be any grey areas between the black and the white. Then I had to fix the edges so they did not look so "blocky".

Hope I didn't break the rules, they just said to use the "shape", which I did
