Long and short of it, just as Black Ops was released Microsoft put in a patch to stop Jtags going online.
It was only around MW3 release time it started going public and servers came around letting people online.
So naturally then the focus was modding MW3, not BO, and at the time people hated BO so it made sense.

Crippy wrote Just downloaded from mobile and it's fine. It's from XBOX360lSBEST's channel. Use ad blocker if you can't get to the download.

Found out the problem I was a using a crappy download manager Chrome downloaded it now

It's mostly the the cods after BO that are modded you'll barely find anything for bo1 but like they say just keep looking on yt there's bound to be some decent ones unless you wanna pay for a menu or tool.

Tbh I wouldn't worry too much about bo1 menus, there not that good considering you can't set stats by menu even if you have matrix or destruction
