mod loader

i have search a lot on google for modloaders
can someone make a tutorial or a link than i can go use mods
i have see somethings like the extremebunkermakerV1.0 but how to use it
i doesn't now it :S
so maybe a little tutorial for how to load it
(i have download its modloader and modselector for itsmodloader but it not works :S )

also thanks

I don't know, I'm not using mod loaders, but have you tried searching here around. Not just for the Its modloader, there may be some other working ones

I have searched but the only one I know is itsmodloader?
Itsmodloader is also still not working for me !
Now i have this problem: When I start itsmodloader, everything is ok.
But when i start black ops than msg comes up: An unknown error has occured.
This message comes up in itsmodloader so it has nothing to do with bo
