plus 3hrs of transport

Oof. I hope you can at least bring along a good book. (Or a laptop....) I've got about an hour each way by car, myself. It's not the full-time work that kills free time; it's that commute. :P`

there is that FF4Edit program

Yes. Perfect for cosmetic edits, but mostly just a tease. (...unless he ever released a version past 1.0.) It really broke my heart back when I first met it. ;_;

Actually...

Would you happen to know how to find/edit the triggers that take you from the world map to a town/dungeon?

Right now, if you use FF4Ed to, say, place a copy of the mist cave entrance 3 squares from Baron, walking onto the new cave entrance will send you not to the mist cave but instead to the (normally impossible to reach) NW corner of Baron town. Fixing that would be a huge step toward what i was hoping to do with the game.
