- vrend410.mng: the production firmware, a HARD dependency of the committed
live pipeline (emu_main.py MAPS['vrend410'].fw loads it) -- the repo couldn't
run the live renderer without it.
- txdn_probe.py / texstore_trace.py / texel_trace.py: standalone reverse-
engineering probes (texture-source/DRAM-write/texel tracing) documenting the
texid-binding and texel-format investigations.
- .gitignore: exclude the firmware-decomp run artifacts (emu860c.pyd rebuildable
from source, *.log/*.pkl/*.png renderer outputs + caches), editor junk, and
the game runtime state/logs written by running the pod.
Left untouched deliberately: the parallel Mech session's in-progress
restoration/source410/BT/{EMITTER,BTPLAYER}.CPP edits (theirs to commit) and
the tracked game runtime state (LAST.EGG/CTMIX.CFG etc. -- transient).
