@Dolphman I can't quite find where I was looking at it before, but I think there was a shikadi.net forum post where a person had made a RoC map viewer where pressing F3 would create a graphics dump. Using this worked for the most part, but I had to make sure that I had the right map loaded to get the right palette for a lot of these. The issue with the Lava Demon was that the map starts with a pitch black palette and then moves through palettes to create the illusion of the room lighting up to reveal the demon, so I had to go through the color table and totally remake the palette based on screenshots.

One of Apogee's overlooked gems. Also, How did you manage to rip the sprites?
I'm looking at Camoto Studio, and it's not listed with the readable games.
