I used wfowler1's BSP Decompiler (GitHub), along with his LibBSP, to convert MOHAA's original .bsp files into .map files. His program hands-down does the best and most accurate .map restoration I've ever seen.
It took less than 15 seconds to create all these, and it's not fair if I don't at least share them with everyone. Below is a .zip file of all the .map files for MOHRadiant.
Note: Some maps like m1l1 and m5l3 are crashing MOHRadiant when holding-right click and panning through the map too much (only zooming in/out works fine). Not sure if there's a fix for that.
