If you have the official FF3/6 ROM (SNES), you can edit it with the editor found on the above page. You can change messages, hero data, items, spells, etc. The only thing you CAN'T edit are the in-game maps. You can edit the world maps a little, but the warp points have to remain the same. It's pretty cool, check it out.![]()
