Type 21 overlay comment update (Found the drawing routine in the disassembly and checked the original for how the oxygen gauge during the first arcade sequence looks like. They're some kind of sprites most likely and not just simply filled rectangles).

-	// FIXME: Looking at Operation Stealth's disassembly I can't find any codepath that
-	// will draw a type 21 overlay. But looking at the first arcade sequence's scripts

+	// Type 21 overlays aren't just filled rectangles, I found their drawing routine
+	// from Operation Stealth's drawSprite routine. So they're likely some kind of sprites
+	// and it's just a coincidence that the oxygen meter during the first arcade sequence
+	// works even somehow currently. I tried the original under DOSBox and the oxygen gauge
+	// is a long red bar that gets shorter as the air runs out.
