best places?

i've got the sppf and ppf stuff figured out but can someone recomend some sites with really cool patches and mods?

 

you could google them and a million of them.

 

yeah i know, all the ones i go to suck, they're just stupid little mods, nothing like the ones where you can get A.I. in coagulation stuff like that, i've found that one before but i couldn't find it again. do you anything about that mod?

 

that mod is found on files.halomods.com

 

hey is it possible to have a (for example) normal unmodded map and a modded one on your xbox at the same time so you can switch between them?

 

yes

 

anything special to it or just put both of them on their and name them different? and also if anyone knows what is the yelo trainer thing i need for some A.I. mod maps
