- dpl2d API fully recovered from the binary recorders (@487f34-488630):
opcode model (points/lines/polyline/circle/color/width/matrix/push-pop),
CallList = INLINE include (state persists to caller), centered coordinate
frame (unit = half viewport height). game/reconstructed/dpl2d.cpp rework.
- BTReticleRenderable ctor @004cc40c transcribed with the authentic
calibration (originX .35, originY .25, scaleY .5, 0..1200m right range
ladder, bottom heading tape, FUN_004cd938 tick ladders, lock rings,
turn arrows); range caret slides from the live target range fed by the
mech4 targeting step (BTSetHudTargetRange).
- Weapon pips: the binary gate is IsDerivedFrom(0x511830 =
MechWeapon::ClassDerivations) [T1: part_014.c:5386 hard-aborts on missing
weapon attrs; part_012 counts + roster ORs capabilityFlags@+0x334] so ALL
7 BLH weapons register (3 lasers + 2 PPCs + 2 MissileLaunchers). Pip A
(lit, authored PipColor) on TargetWithinRange, else dark ring B.
- AddWeapon @004cdac0 store map corrected to the verified order
(part_014.c:4827-4837); both state attrs are literally named
"SimulationState" (strings @51d526/51d577) -> weapon simulationState.
- Mech roster this[0x1ef] renamed poweredSubsystems -> weaponRoster
(0x511830 is MechWeapon, not PoweredSubsystem=0x50f4bc); derivation-tag
table added to context/decomp-reference.md.
- Draw hook BTDrawReticle after the 3D scene, cockpit view only. Binary
Execute @004cdcf0 is an un-exported gap -> Draw dynamics [T3], tracked
in context/open-questions.md with the blx_cop canopy + PNAME pip meshes.

Every dpl2d_ recorder in the binary self-identifies via its debug-name string
(part_010.c 0x487f34..0x4888c0) -- the complete API + opcode map is recorded
in phases/phase-02-dpl2d-reticle.md: point sets (2/3), closed polylines (4/5),
open line strips (6/7), AddPoint (8), AddCircle (9), SetColor (0xF),
Set/ConcatMatrix (0x10/0x11, 2x3 affine), Push/PopState (0x12/0x13),
SetLineWidth (0x15), CallDisplayList (nested glyphs), FullScreenClipRegion.
dpl2d.cpp reworked to that model: command-stream recorder (open-primitive
vertex runs, state commands, nested list calls) + a recursive ExecuteList
rasteriser (XYZRHW points/strips/loops/circles, 2x3 transform + state stacks,
save/restore). CORRECTION: the old "PushMatrix/MoveTo/PopMatrix" trio was a
misreading of OpenPolypoint/AddPoint/ClosePolypoint ("draw a point") -- kept
as aliases mapping to the true semantics.
Reticle findings recorded: the ctor (@004cc40c) builds ~15 display lists (the
dotted-cross reticle, tick ladders via FUN_004cd938, side arrows, arcs) plus a
3D marker chain and the PNAME1-8.bgf pip meshes (all ship). Next: transcribe
ctor+Execute, wire the 1996 caller's AddWeapon arguments, hook the draw.
