Im new to all this modding stuff...about a month ago i got my x3 installed and now i want to do some modding to halo mp maps i got cache editor on my xbox i now how to use it...i really was to kno how you can get your own weapons and maps to work on xbox. Also i dowloaded the nmpi and hmpe map pack and installed the maps on there are amazing and i want to do something like that. i downloaded this single map it comes with a 67 mb map which is the silent cartographer MP and a conversion file .pff which lets you play the map but i dont kno how to get it to work. someone set me on the right path to excellent modding
