Does anybody know how to take a normal halo map, and decompress it, and keep it decompressed?

Yeah... keep a cache file

nah cache files get annoying. I just used this other prog, it worked perfect

So if you just used this program then way are you asking

get the cache file.. (should be something like map003.map or whatever)

rename to what its really called and (im assuming you have halo on hd..)

replace with what you have in

games>halo>maps

IF you replace a map with a cahce file, it won't work. You have to Compress the map, then you could replace the default map...
