Good evening,
A new version of ioRtCW just got released; So far, this is the most complete work done on the source regarding modern systems support: it’s been merged in RtCW Co-Op for instance, and probably be used for Berserker@RtCW 
Changelog and download for all systems:

Feel free to report bugs and issues there or on IRC
Thank you!
Thanks, Mateos. I have an interest in the ioRTCW engine (for possible future projects). 
Could you please fix this issue? https://bugzilla.icculus.org/show_bug.cgi?id=6048
I am currently in the process of recording & uploading old competitive matches on youtube and it would help a ton if i could process it automatically with IGMDB’s renderer instead of manually recording (it would save me months of time)… there is a huge demand for these matches
Greetings

M4N4T4RMS Sorry for delay on post. This version was put together in late November.
— Source: Official topic of Wolf 1.42b (aka iortcw)
Since January, I use a modified build of iortcw for my upcoming mod and (in the console, I can see) it is version 1.42b.
Anyway, thanks for sharing his works as he contributes to what is the future of RtCW, with his new engine.
