Thanks Rob, how the heck are you finding the 1bit maps?

I'm not sure of the correct name for different references (map, constant, array, etc.?)I know for instance, that KRKTE is a constant, I look through the hex until I see the same pattern in the hex. I think it takes some time to get used to hex, but I know the more I look, the better I get at "seeing" it. I hope that makes sense?

Fwiw, I don't think it's to hard to define 90% of a file just by comparison. There are some bits that I think the only way to really find out is to have someone disassemble the file. Hope that helps.
