Three unrelated source-data bugs surfaced while round-tripping our own
Content/Mechs tree against the decompiled V4H packages. All three were
found because a decompiler verifier disagreed with the shipped data, not
by inspection.
Hellspawn / Sunder: unterminated section headers
-------------------------------------------------
hellspawn.subsystems:101 [HeatSink10 -> [HeatSink10]
sunder.subsystems:120 [HeatSink16 -> [HeatSink16]
The notation parser keys a page on the bracketed name. With the closing
bracket missing the page name is malformed, so that heat sink's block is
not registered as its own page and its Model/ExecutionState/
InternalLocation keys are absorbed by the preceding page. Net effect: one
heat sink silently missing from each mech (Hellspawn LeftTorso, Sunder
LeftArm), and the preceding sink's location keys overwritten.
CauldronBorn: undefined macro in TwistRadius
--------------------------------------------
cauldronborn.torso:15 TwistRadius=$(OBSTUSE_TRADIUS) -> 100
OBSTUSE_TRADIUS is a typo and is defined nowhere in the define tables;
the intended symbol is OBTUSE_TRADIUS (=140). An undefined macro does not
fail loudly - the factory substitutes its own default - so this shipped
for years as a silent fallback.
Resolved to the literal 100 rather than $(OBTUSE_TRADIUS) because the
compiled .torso record in the shipped package holds 100.0f, i.e. the
factory default that has always been in effect. Using 140 would change
long-standing behaviour; 100 preserves it and makes it explicit. Verified
against the packaged record: verify_smallmodel now reports 1280/1280 keys.
Lesson recorded: an undefined macro is not a build error here. Check what
the compiled package actually holds before "correcting" a symbol name.

Battlemaster stock loadouts (Content\Mechs\Battlemaster\battlemaster.subsystems):
- Replace lone MediumPulseLaser with full IS stock: PPC (Special2, group 1),
6×ML (3 RT + 3 LT, group 1), 2×MG (LA, 200 rds, group 1), SRM6 (Special1,
15 rds, group 2).
Battlemaster Clan 2C (battlemaster2c.subsystems):
- Replace ClanMediumPulseLaser with: ER PPC (RA, group 1), 6×ER ML (3 RT + 3
LT, group 1), 2×Clan Gauss (LA, 16 rds each, group 1), Clan SSRM6 (Special1,
15 rds, group 2).
Behemoth / Behemoth2 (.subsystems):
- Move Gauss rifles from weapon group 3 → group 1 (3 occurrences each).
Resource builder (build-resources.ps1):
- Always run with -window (windowed + DDrawCompat). Fullscreen native DDraw
fails on VMs with the generic Microsoft display adapter.
- Remove dgVoodoo2 D3D interceptors (D3D8/D3D9/D3DImm.dll) from Gameleap\mw4:
they silently break the builder (process exits 0 without packing anything).
Script also defensively moves any such files aside via $dgvMoved block.
- Remove dgVoodoo.conf and dgVoodooCpl.exe (abandoned experiment, no longer used).
- Expected: 'Hardware Error: not compatible with MechWarrior 4' dialog at end
of build on VMs -- click OK, packages are built correctly regardless.
