Why to bother with all this? I use (successfuly) the same method as on my debian-box. I've put Doom2.wad file on MMC and then went to /usr/share/lx-doom/wad su-ed renamed oryginal wad (I didn't want to remove right now): mv doom1.wad doom1.-wad created symlink to mmc: ln -s /media/mmc2/DOOM2.WAD ./doom2.wad voila My all id games on my PC work that way for their "big" PAK's.
