Caution... there is a new mac update for Unreal Tournament 2003 called v2225.1. You can find it at here at macgamefiles. Although it includes some great things (new efficient openal, and a hue fix for the panther-ATI Radeon bug), it breaks compatibility with .u files compiled PC side... in other words, if you install v2225.1, full conversion mods (such as my precious Frag Ops) will not work! I have not spoken with the mac BTs from Red Orchestra or America's Army yet... although I assume AA compatibility is fine since the author of 2225.1 (icculus) also wrote AA for mac. The offending file is the 2225.1's brand new ut2003-bin file (the actual game launcher) located in the SYSTEM folder visible when you right-click (or option-click) Unreal Tournament 2003 and select "show package cotnents". I am trying to talk to the author (Ryan Gordon/Icculus) to see if there is a fix. The culprit seems to be a defunct (1K) texture file called InstagibEffects that remains on the pc and mac v2225.0. It's there in the compile of the .u file, even though our mod (FragOps) does not even use this instagibeffects. However, the OpenAL audio implememation of v2225.1 is fine. You can download and install it separately at http://icculus.org/~icculus/tmp/openal.dylib.bz2 Just unstuff, and copy openal.dylib to your UT2k3 package's SYSTEM folder, replacing the original openal.dylib. _______ Note that the Panther hue fix is great, and the other optimizations are great. I have not tested joining internet servers runnin on PCs, but from looking at Icculus' previous notes, I would assume it does not break cross-platform multiplayer compatilbility.
