The video dump from yesterday was pretty reassuring. I had wondered about Gauntlet II. Historically a very finicky game in classic PC(Windows/DOS) emulators. Known to have scrolling issues with the floor vs the solid score bar at bottom, or if it did move you got a line of flicker on the edge. The other being gross audio problems with all the arcade recorded samples spit out from the DPCM channel usually being off pitch, cut, or not run at all. That emulator they coded shows none of those issues.
