Ok for all those who have the "expected version 6" error, try the following:

Download the following file:

ftp://www.mirrorservice.org/sites/qu...elease_132.exe

Install it in windows even if you have not got quake 3 installed, When it mentions punkbuster just say no.

Navigate to "program files/quake 3 arena/baseq3"

Copy all the PK3 files in that folder to the "home/user/.q3a/baseq3" folder on your n900 (overwriting any files of the same name).

Play Quake 3

Let me know if it works. Thx.

Edit: Changed the directory for the n900
