Still have an openpandora lying around, though I’ve mostly used it for ports of dos games, either open source (openxcom, openttd, scummvm etc) or M-HT’s recompilations (xcom, tftd, warcraft). There is a successor by now (the Pyra), but it has a hefty price tag for (in my use case) not that much more.
Lately, since for some mysterious reason I have been travelling less, I’ve been using the raspberrypi more. The pi4 has one major advantage over its predecessors; it finally has enough oomph to run munt (mt-32 emulation) at full speed. That way I can play all those games with the music as I remember it, as opposed to how it actually sounded back when I played them ^_^.
