1. Anonymous asked: I'm not sure how to set it up so I can use it, I try to activate it and it says that it's missing files

    Try using the version 1.3 (on Windows) or 1.2 (on Dreamcast).

    Besides this, which files are missing? All you should need is to add the file PAK0.PAK (and optionally the file PAK1.PAK) from your version of Quake to the ID1 subdir before playing it.

    Sorry for the late answer.
