That's exactly what he's trying to do -- automatically turn hyphens in his URL into underscores, so that they will map to controllers/methods without needing routes.

CI 3.0 added this feature. I suggest either:

A) Update your application to CI 3.0. You can find the in-progress dev version here.

B) Extend the Router class and replace the _validate_request() method from here.

Note that there may be other changes in this method that I forgot about that may affect your app. I don't remember everything off hand, but that's where the str_replace stuff happens. So might get you in the right direction for now.
