g3_bitmap_common() (Bitmap.c) used the same bm_w/bm_h for both the
on-screen quad size and its texture-coordinate bounds. The former
should use patch 04's native-size override for a modded/upscaled
bitmap; the latter must always use the bitmap's own real dimensions,
since that's still what's actually being sampled. OpenGL never hit
this (opengl_bitmap() ignores these bounds and always maps the whole
real texture), but the software renderer's h_map() takes them as
literal pixel coordinates to interpolate, so the override capped how
much of a larger bitmap it ever read - cropping anything past the
original sprite's bounds, such as an upscaled critter's limbs.
Split into a separate tex_w/tex_h pair, always the bitmap's real
size, used for every texture-coordinate computation.
README.md: document this, and the previously-undocumented
engine-debug-tools RSD8 decode tracing patch (02).
- 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.
Extends the MDL system beyond text overrides: bitmaps/<label>.json
names a model/scale and resource list, and mdlp extracts each
resource's frames, runs them through an ONNX Runtime CPU upscaler
baked into mdlp-image, re-quantizes to the game's palette, and writes
the result back - same build-time pipeline as message overrides.
Adds animgallery, a standalone viewer that renders any data
directory's animated resources as an HTML/GIF gallery with a
checkbox-driven MDL JSON generator, and -only-changed to preview just
what a mod overrides against the base game.
Fixes a real data race in hacked's ChangeNotifier.hashAll() (found via
go build -race causing non-deterministic resource counts), via a new
numbered patch rather than editing the vendored source.
Adds engine-patches/, a general-fixes counterpart to
android/engine-patches/ now staged and applied to the desktop builds
too (previously unpatched): a real GL_UNPACK_ROW_LENGTH stride bug, an
audio error-logging improvement, and two critter-rendering fixes -
mod art was losing to the base game's own re-opened resource files,
and critters rendered at the wrong size/position once that was fixed,
both from how the billboard renderer derives on-screen size and
placement straight from bitmap pixel dimensions.
Updates README.md and AGENTS.md to document engine-patches/.
