Although EDuke32 has been released under the GPL, the game data (graphics, sounds, levels, etc) is still proprietary. For Duke Nukem 3D (eduke32), there are a couple of options: - Buy the game, and copy DUKE3D.GRP and DUKE.RTS file from the game CD to /usr/share/games/eduke32/ or your ~/.config/eduke32 directory. Note: DUKE3D.GRP should be named "duke3d.grp" (lowercase), but DUKE.RTS should be uppercase. - Or, install the eduke32_shareware_data package from slackbuilds.org. This only gives you the first episode of the game. For Nam/Napalm (eduke32): 1. copy NAM.GRP or NAPALM.GRP to /usr/share/games/eduke32 2. copy GAME.CON to /usr/share/games/eduke32/NAM.CON (or NAPALM.CON). Do NOT name it GAME.CON, or Duke Nukem 3D will fail to start! For WW2GI (eduke32): 1. copy WW2GI.GRP ENHANCE.CON, XDEFS.CON, and XUSER.CON to /usr/share/games/eduke32 2. copy GAME.CON to /usr/share/games/eduke32/WW2GI.CON (again, don't name it GAME.CON). For Shadow Warrior (voidsw): - Buy the game, and copy SW.GRP to /usr/share/games/eduke32/ - Or, install one or more of these SBo packages: jfsw_demo_data (shareware; first 4 levels only) jfsw_registered_data (full game) jfsw_wanton_destruction (expansion pack) jfsw_twin_dragon (expansion pack) (Yes, voidsw will find the game data in /usr/share/games/jfsw) For Ion Fury (fury), presumably you copy the .grp file from the game directory to ~/.config/fury. The engine doesn't look anywhere else for the data files. I don't own this game, so I can't go into more detail. If you do own this game, email me with the details and I'll update this documentation.
