Wow! fully ported to gles?
Actually I put Quake3 up last week.
Should be buildable with libs from the debian rootfs.
There's also a suitable toolchain in:
(although any arm one should do).
You need the pk3 files and CD key from a real Quake 3 CD.
In theory this should work with openarena pk3 files, but it will need a merge with a newer version of the quake3 tree.
As it is, the pk3 files are rejected, and the code that loads them has been modified since we branched.
If anyone fancies trying the merge, feel free.
