- engine-debug-tools/: a debug dump hotkey + dump2png to inspect
decoded critter frames independent of the renderer (see root
README.md's "Debugging" section).
- engine-patches/04,05: fix critter sprite scale and an OpenGL
texture cache collision, found using that tooling.
- mdlp: fix encodeFrames RLE-diffing upscaled frames against a
previous-frame reference the real RSD8 decoder never implements
(verified against Night Dive's original Mac source down to the
68K assembly) - was rendering as scattered static in-game.
- Upscale pipeline: better color quantization (dithering, pure-ramp
exclusion) and per-resource model selection.
