Fixing Event Trigger Corruption

I have been working on my hack for almost 8 months now, and have just now discovered that in the very earliest build of my hack, there was corruption on the event triggers on maps $192 (Ancient Cave Save Point) through $19D (Colosseum) (Note that some of the maps do not have events). I have learned my lesson to never use Zone Doctor ever, EVER again for map edits, but for now, I'm just looking for how to fix it. The event triggers themselves have no changes, so just copying a block of hex from an uncorrupted rom should do it. Where do I find the offsets for those events?
