It appears like there was some progress made on getting RTCW running on a Raspberry Pi but it was running quite slow. The last update was 9 years ago so it's likely they were using the original Raspberry Pi. Maybe it could work with a newer model. I don't know.
It's not what you are looking for but you might be interested in RealRTCW.
