Are you talking about patching a modded map into an existing map or adding a mod-map? If so, you need 2 tools, ppf-omatic and encrptomatic signature. Put a clean copy of the map in the top field of ppf-omatic and the patch in the bottom one, apply, sign with encryptomatic and you are done. It is a good idea to save a clean copy of the map on your pc or in a file on the xbox so you can change back if you like. But, since we all own halo2, you can just get the file from the original. These tools and tutorials are available on halomaps.com. Cannabis island is a trip for ascension! ppf-omatic default looks for isos, so you will have to tell it to look for all files or when you go to enter your map, you won't see it listed as one of your files.
