Port Status

Here is a table of the most up to date information we have regarding icculus.org/Quake3's working status on different operating systems. There are things to bear in mind when viewing this:

The status column refers only to the latest information we are given, so it may be out of date.
"Working" doesn't always imply "usable", see the Notes column.
Status is one of working, broken or unknown.

Implemented Features

OpenAL support for sound. Surround sound supported.
SDL being used for input, OpenGL context management, and sound. Though not on Windows yet.
Colors converted to ANSI escape codes in terminal output. (set ttycon_ansicolor to 1 to enable this.)
More supported platforms, see the table above.

PunkBuster Support

Even Balance's Punkbuster support can never be included with any open-source version of Quake 3 due to it being removed from the source-code before the release, and the binary-only nature of its anti-cheating software.

While it is possible that someone could write an open-source equivilant of PunkBuster, it's not very feasable for a number of reasons.
