That's right. Zip the files with detailed instructions (like in a README file) on where to add what. They add the maps, images, whatever, and then re-open the game. I suppose that's how it's done.
(And AlwaysIdeas! I dunno if you got my PM, but I am assuming you didn't. Check my last reply to your topic about Mythical RPG as soon as possible, please. Then we can discuss the details on what you want me to help with, etc.
Also, I joined your current forums.)
