Hello, I actually run Arch and i got yadex installed via compilation of the AUR package via makepkg and installed it correctly via pacman. The problem is that when I'm starting yadex with the -i1 option (if i got things right from the --help, this option is used to load a DOOM1 WAD file) I got this output : [nelson@posix ~]$ yadex -i1 DOOM.WAD Yadex 1.7.0 (2013-07-13) Reading config file "/etc/yadex.cfg". Reading game definition file "/usr/share/yadex/doom2.ygd". Loading iwad: /usr/share/doom/doom2.wad... /usr/share/doom/doom2.wad: No such file or directory Error: If you don't give me an iwad, I'll quit. I'm serious. It looks like yadex ignored my argument :) More "bizzare", when i load the same doom1 file, but with option -i2, the editor is starting : [nelson@posix ~]$ yadex -i2 DOOM.WAD Yadex 1.7.0 (2013-07-13) Reading config file "/etc/yadex.cfg". Reading game definition file "/usr/share/yadex/doom2.ygd". Loading iwad: DOOM.WAD... ** Welcome to Yadex. Glad you've made it so far. :-) ** ** ... What I'm scared of, is that yadex is loading a 'definition file" for doom2 (at least it's what I'm understanding) with a doom wad file ... Is that all right if I just work with -i2 on doom's WAD ?
