For anyone interested, I have a command-line utility to list and extract files from RES files: https://github.com/Shiryou/brut/releases/tag/nightly

Sadly, RESUTIL converts PCX files to a non-standard bitmap format before submitting them to the RES file and doesn't re-convert them during export. Adding files to RES files is next, so I have to tackle the conversion anyway and will try to write a reversal function.

For now, only FLC and WAV files export as one would expect.

Here's how to use the program:

Usage: resutil resfile-name [[s nnnnn] [c] [n] [r] [u] [+|-|e sourcefile-name ]] | [l] | [v]
   +  add file
   e  extract file (does not remove it)
   x  extract all files (does not remove them)
   hc use CRC hash (default)
   hi use ID hash
   l  list contents of resource file
   n  do not rotate PCX resources (default)
   u  do not compress resources
   v  verify resource file

EDIT:
9/7: It can now add files, but it doesn't support compression, rotation, or PCX decompression (as mentioned above) yet.
9/9: PCX decompression is now supported. There are also builds for Windows, Mac, and Ubuntu.
9/10: PCX rotation is now supported. We're almost there! Just LZSS compression is left before we have a RESUTIL replacement. Then, I'll try undoing rotation and PCX decompression and move on to creating a GUI.
9/15: I've been able to confirm that editing a resource file works. Check out a video of replaced images in the intro sequence.
