Actually I had this project in suspension for some time. Your map just reminded me of it. You're asking about the game generator or the Microdem one?
Btw. can you see the screenshot? I can't.
Damn screenshot bug, where's my insecticide canister?
And another thing. I strongly suggest that you download SCRACC (http://members.shaw.ca/scracc/) and use it to create your config.bmp's. Reading the Omnibus tutorials may help also.
