I just downloaded the SmashQ3 mod mentioned on games.macnn.com and noticed that it was dll based, versus vm based, meaning it was written as a windows-only mod. Most Q3 mods are vm based, Q3 compiles the code changes dynamically, but the dll based mods are precompiled for Windows only (another excellent example of this is Rocket Arena 3. the most popular quake 3 mod and we can't run it due to the way they wrote it). If anyone has had any luck running Smash Q3 on their Mac (even though its technically impossible) I'd like to hear how.
