So how to install it? What do I need? Lets start with what you need:
MinGW compilation support on Windows and cross compilation support on Linux.VoIP support, both in-game and external support through Mumble.OpenAL sound API support (multiple speaker support and better sound quality).Many features where implemented like the following (from their project site): Iortcw is an enhanced RTCW engine – id software used to release the source code of all their games back in the day – with some features of the ioquake3 engine. Something we only dreamed about back in 2001. After trying to get the game to run with WINE and PlayForLinux without success, iortcw finally started without any issues in impressive 2560×1440 resolution. Finally found a way to play one of my all-time favorites “Return to Castle Wolfenstein” on a modern computer (and under Linux) with the engine port iortcw.
