The current main branch may be ahead of the released mod files. For compatibility, switch to the corresponding release tag (latest at the time of writing: 5.4). You can return using git switch -.

# Switch to tag 5.4 to match 5.4 mod files
git checkout tags/5.4

Build

# Run from RealRTCW directory
make

Output files are in a subdirectory under build directory.
