Oh my. TDM, Devnulmod, and Zippy's mod are all mutually exclusive and incompatable with each other. The reason is that Devnulmod and Zippy both alter (extensively) the components in the game. TDM, on the other hand, intentionally _only_ mod the AIs to make them as strong as possible for the standard game. I think the Dev is working on creating Versions of the TDM races that is compatible w/ his mod, but I don't think it's done yet.
Now, don't get me wrong; you can play all of these mods. But you can't play them AT THE SAME TIME, IN THE SAME GAME. Each of these three mods needs to be in it's own mod folder; and you alter the path.txt to point to whichever mod folder you want to play at that time. That way you can easily switch between mod; all you do is change path.txt.
Confused yet?
