In 2011 I started browsing the latest graphical/sound quake mods, putting together a pretty build using LordHavoc's darkplaces, rygel's ultra textures packs, the reforged packs and a variety of mods, to play quake original. Anyone can do the same, however the hassle comes when you have to browse the quakeone forums, stumbling to find the posts which detail what cvars and what configs/files you have to overwrite etc in order to get each mod to work. I literally spent as much time getting the mods working as playing the game. So I put together a nice-looking build of quake original and it's expansions called epsilon for everybody to get into, without getting into the hassle of config files and searching to find every available mod then getting them to work! The main quake build also includes the original shareware first quarter of the quake game - it is easily upgraded to the full game by dropping in the pak0.pak and pak1.pak files from the full game's id1 directory (more details below).
This should fix issues for players who are not able to launch quake epsilon or it's expansions, or arcane dimensions, from the original batch files. DO NOT DOWNLOAD IF YOU'RE NOT HAVING ANY PROBLEMS. Alternatively, try right-clicking on the original batch file and 'Running As Administrator'.
To install, unzip to your quake epsilon folder. Overwrite the existing batch files.
Please note this contains the batch files for all quake epsilon expansions, and Arcane dimensions.
If you have the epsilon build of arcane dimensions, copy the "arcane dimensions.bat" file to your arcane dimensions folder and allow this batch file to be overwritten as well.
Hopefully this should fix issues that some Win10 users have been having where expansions failed to launch.
If it doesn't please leave a note in the comments.
