ya this is really simple. open up whatever hex editing program you have. i use hexedit. at the top you should see the map name like bloodgulch. it wont have the .map thing at the end. then take that and change the name however u want it. ill make an example. lets say you want the map name to be pancakes. you change "bloodgulch" into "pancakes" (without the quotes) and save it as pancakes.map. keep in mind if you change the name to pancakes then you HAVE to save it as pancakes.map otherwise it wont work. another example would be changing the name to pie. after you replace "bloodgulch" with "pie" (without quotes) then you must save as pie.map
o ya it doesnt have to be bloodgulch it can be any map you want

sig to large.
