Okay. I can give that a try too. But shouldn't simply selecting the already-modded minecraft.jar work? Without having to make a BTW.zip at all? I guess that's what I'm really asking.

So I have struggled for a little while trying to get BTW working with Magic Launcher (I use ML to manage different versions for various mods and different servers I log into that haven't updated. It makes things extremely convenient!). Well long story short, can't get it working with Magic Launcher....
