Team up, start a formation of dedicated hackers and helpers. Here, you can discuss production of hacks with other groups, or make your own hacking group.
No not like that I've an idea. Only one person would have the main file and all others should post their works(in .zip format).
For maps we can save them by going to file. Each tool make a file in same folder as the with some extension which contains the data/mods we made in the games, if we post them it is easy to compile them into one game.
I am saying that we should create the ips file with the original game. Share the ips patch. Scripting would most probably not require the presence of the the modified game, as it can be applied anytime, easily by the compiler. Besides, we can start a google project (They allow uploading files there)
