since ThinIce dosent explain anything, here is your answer.

download MOHAA Tools 1.3 from this site. open the prog and load up the map's .bsp file that you want to edit. then click Create Original .map file. after its done, open Radiant and surf to where the .map file is placed. open that in Radiant and prepare for one hell of a resteration job.

the conversion will destroy most of the map, but with due time (100+ hours), it can be done quite well. lemme know if you need any other help.

cya.
