Doom is a terrifying, bloodthirsty game involving running around dungeons and shooting at monsters. It is probably not for young children, but is great fun for older ones.

How to install

The following instructions need to be run from the Terminal activity. You will need a working internet connection on your OLPC for the install only. The instructions worked on a B4 OLPC laptop running Build 650.

  • Open the terminal
  • Switch to the root user, by typing:
su

...and entering the root password, if requested to.

  • Then type
yum install prboom
  • The download is about 18MB, so will take a few minutes.
  • When you get a prompt again, type:
exit
  • To run Doom, type
prboom

Changing Doom to run in full screen mode

To run in full screen mode, type:

prboom -geom 1200x900

To permanently adjust Doom to run in full screen mode all the time, type:

cd /home/olpc/.prboom
nano prboom.cfg

This will open the doom configuration file in the nano text editor. Find the two lines in the file with the words:

width         640
height        480

And change them to:

width         1200
height        900

Then type ctrl-x to exit, and type y to save your changes. Now, Doom should run in full screen mode when you type

prboom

Don't have nightmares...
