As Zygmunt stated, the two codecs are related but not identical. The GR-216 should be capable of decoding both codecs, but beware of problems with the quality of the GR-216. I received a lemon which Gospell failed to fix under warranty since their terms for doing so were unacceptable. You just may get enough lemons to make lemonade, but not much else. Again, beware as I eventually trashed my GR-216. As far as firmware, I can't remember the exact revision, but Alokesh Gupta had posted a link to the firmware... in 2019, I think?
