Guess I'll have to double-post since I have more progress to show. For starters, I finally got custom Zone titles working. So far, I've renamed the first five Zones.
Emerald Hill = Verdant Coast
Chemical Plant = Night Skyway (This one's subject to change. The A in "Skyway" appears discolored for some reason.)
Aquatic Ruin = Marsh Palace
Casino Night = Spirit Casino (It's a reference to the local River Spirit Casino. I got inspired to name it that, and change the palette again, by passing the RL casino on the way home from an ophthalmologist appointment.)
Hill Top = Magma Bluff
I've also finished Marsh Palace Act 1.
