k ive been trying to make weapons like the sniper rifle fully auto and ther is a tut at halomods.com but it never works for me. first thing i do is get the map (bg) then decompress it in halo hacker tools and then open it in hmt and do all that stuff and the compress it again and then ftp it into the xbox but IT NEVER WORKS!!!! somone show me how to switch around the projectiles and how to make fully auto weapons and tell me wat im doin wrong....THANX in advance

I don't know what kind of stupid tutorial you read, but you shouldn't have to decompress/compress anything. Just edit the cache file itself...
