I'm using vavoom with the 3D models and HiRes textures. Looks great, but when I starting some add-on files the 3D models and HiRes textures are wrong (of course). So I need vavoom with and without enhancements. Two vavoom installations was not a option. A quick hack that works is to copy the corresponding directory (e.g. basev/doom1) to a different name. One with and one without the enhancements. Adapt the file base.txt in that directory and insert a new option into games.txt.
I know, this is only a workaround, but did anyone know a better solution?
By the way, did anyone know a graphical vavoom launcher for linux?
