I prettymuch make all the PSP layouts, except an update was just issued with Half Life 1 which makes DPB Unplayable at the moment. But let me know if you need help mapping. Mapping is pretty fun except theres no where to play it atm.
I can't even test the map in a local game, I can't move the mouse away from a small square in the middle. Did you get the Map Viewer on BYOP to work for you? I am on Windows 8 and it just freezes up when I go to file>open
Yeah the game wont let you move the mouse, this is due to the half life 1 update a week ago. Since that all HL1 mods are prettymuch unplayable. I dont know with mapviewer is, I just decompile and put it in dpb.
