Hi Matt... do you have a disk manager? Disk manager 2 or DM2000? With this you could copy to a new disk.
I have used the ToD editor and it is quite tough to use... but it's not bad, once you get the hang of it. There should be a game ON the editor disk already. You don't need to worrk about copying, really... have one blank diskette for saving your game to. I can't remember, but I'm pretty sure you can save your progress, and when you do that, simply pull out the ToD editor disk and insert your new disk. It will prompt you to do this, so you shouldn't have much to worry about. If you're editing already, you're in good shape. For future loading of your edited game for further editing, it will prompt you to insert the disk your game is saved on.
I remember when I got started with my ToD Editor project. =) It was for a little game called "Legend of Beryl Reichardt" which started in the ToD editor and now has life in a standalone RPG project currently in development. I remember doing my graphics porting from the ToD game to XB...
These are 2 pics of my graphics work bringing it over from the ToD editor game:
This is a pic of my current game work... battle screen in the game.
