I don't know if somebody has mentioned this already, but if you don't have the full version handy, but still want to try out Q3A on your N900, you can get the Quuake 3 Demo data files from here:

Install the demo on your PC and copy the pak0.pk3 file from the demoq3 folder to /home/user/baseq3/ and it should work
