Installing Quake 3 on a Raspberry Pi

I found out Quake 3 runs on Raspberry Pi, so I had to install it to my Pi. I managed to do this with the following commands.

cd ~
wget http://dl.dropbox.com/u/1816557/quake3.zip
wget http://dl.dropbox.com/u/1816557/Q3%20Demo%20Paks.zip
unzip quake3.zip
unzip Q3\ Demo\ Paks.zip
rm quake3.zip
rm Q3\ Demo\ Paks.zip
mv ./baseq3/pak* ./quake3/baseq3/
rm -rf ./baseq3/
chmod +x /home/raspbian/quake3/start.sh
chmod +x /home/raspbian/quake3/ioquake3.arm
chmod +x /home/raspbian/quake3/ioq3ded.arm

cd ~/quake3/
./start.sh

I got an error "failed to open vchiq instance", so I had to enter the following commands:

echo 'SUBSYSTEM=="vchiq",GROUP="video",MODE="0660"' > /etc/udev/rules.d/10-vchiq-permissions.rules
usermod -a -G video raspbian

After that it started working and runs like a charm.
