+1 for UMBcast, his @UMBshow Twitter is still active for the curious
DOS Nostalgia also has a podcast, though the YouTube channel is a bit more active.
Lazy Game Reviews on YouTube also has this DOS games playlist. Lately though he tends more toward old PC hardware.
If I might add, my own rarely updated podcast often features DOS games in addition to poor quality audio and an overtired narrator: Let’s Play by Play.
EDIT: Looks like AntennaPod can almost accept YouTube playlist feeds. It recognizes the posts but not as containing media :(. Appears there are some other converters that can adapt them, for the curious.
