Wardad,
First off, thanks for downloading my mod. I'm not sure why you say, "I'd have to create a bunch of picture-empire folders..." You should be able to unzip the files to your Space Empires IV folder and then start the game. Just make sure that you use the AI’s and/or pre-made Empires that come with the game as explained on my
Readme page.
Also, can you tell me more about "the MOD picker?" It sounds like a great idea, but I haven't heard about it before. (Yeah, working on ZippyMod has kept me a little secluded in the SE IV world.)
