There are a few easy steps to take if you want to play this amazing collection of levels.

  1. Get Quake.
  2. Jam9 requires this version of the Quoth mode to run properly. If you already have Quoth and you are unsure of which version you have I would delete the other and start from scratch to ensure compatibility. You can also move or rename your original if you want to save it.
  3. Download Jam9 from here, here or here.
  4. Read the Jam 9 readme file – it has important info.
  5. Launch Quake with the following command line options -quoth -game jam9

You can use the newest version of the Simple Quake Launcher to launch the mod as well. Highly recommended!

Here’s even more info about Jam 9 from my YouTube channel.
