DPCM codecs

Are there any free encoders that can encode DPCM? Not ADPCM, straight DPCM, and I'm not talking about the super-lo fi NES 1-bit variety either. Several old games like Wing Commander 4 or Quake 3 used DPCM according to multimedia wiki but those formats are very hard to find even decoders to nowadays. I think they compressed 16-bit samples to 8 or 6 bits.

I found this while using the -codecs switch in ffmpeg:
DEA.L. roq_dpcm            DPCM id RoQ

E means it supports encoding.

Thanks but how can I try it out? Audacity FFmpeg export fails and produces a 0 byte file.

Does it work if you just call ffmpeg directly from the command line?
