ioq3ztm is a fork of the ioquake3 engine with fixes and features that don't fit in ioq3 for one reason or another. Created to be a better (or alternative) base engine for standalone games. ioq3ztm is not compatible with quake3 game code (QVMs/DLLs/SOs/DYLIBs), demos, or gameplay network packets.

Many things in ioq3ztm were copied from Turtle Arena, which now based on ioq3ztm.

Major Features

• Four player splitscreen, with support for connecting to network servers
• Improvements not compatible with quake3 1.32b
• Better Virtual Machine (QVM/DLL/SO/DYLIB) API handling
• Improved Virtual Machine system calls (unified shared calls and acos)
• Modified pure pk3 system
• Removed code not needed for standalone games (CD Key handling, authentication server code, and punkbuster ui code)
• Ogg Vorbis support, enabled by default (with source headers and libraries for easy compiling using MinGW)
• Joystick select menu

Future Plans

• Support for using a single IQM skeleton animated model for players.
• Ogg Theora video playback support. (It will probably be added into ioq3 as well.)
• Many small fixes and features from Turtle Arena.
