Apparently it looks a lot simpler than I've been imagining this whole time? Though just looking at a few sprites that only show outlines may not be revealing that much information.. Still, we can tell that the memory erasure device goes around the head and sends electrical shocks straight to the brain, while the memory restoration device takes the form of a lantern and seems to base its potency on any available triggers, even just vague recollection. I've heard of certain lights being able to improve focus so maybe the device is based off that idea? No clue on how the (presumed) projection of complete and incomplete memories comes into play though.
