Basicly I was wondering if it's possible to find a "Block" in the Hex editor. No particular block, but a block type. Then do a find/replace all to another block type. For example, say I found the code for a water block. Then I found the code for wood. Then I replace All water in a map with Wood. Is this possible? I was going to try it tonight when I get home, but was hopping someone has already tried it and can give me the results.
