I'm looking to decompile one of the Blue Shift or possibly more SP maps so I can recreate parts. Only trouble is, the two converters I have won't accept the maps. My BSP viewer (which can also handily convert BSP to MAP) gets an unknown error whilst trying to open one of the levels (say, ba_maint.bsp), and BSPTwoMAP.exe reports that there's an odd lump size or something like that. Any ideas?
