Both were already documented as standing repo content (AGENTS.md's critical-files table, several findings.md entries citing D194/D300's ground truth) but never actually committed -- add them so the repo matches what's already written about it. GPLv2, read-only reference, never compiled as part of this build (see reference/mouse-injector/README.md for provenance).

GEPD Edition — Mouse Injector (vendored reference source)
Vendored read-only reference for the PC port's input layer. NOT compiled
by our build; never modify it — treat it like rsp/graphics/gmain.s
(ground truth we consult, not code we ship).
Provenance
Extracted from source.tar.xz inside the GEPD Edition 1964 bundle
(C:\Users\james\Games\Emulators\Nintendo 64\1964_GEPD_Edition\1964\).
The Mouse Injector is a Project64/1964 input plugin that emulates the N64
controller from keyboard/mouse while injecting mouse-aim state directly into
GoldenEye 007 / Perfect Dark game memory. License: GPLv2 (see
LICENSE.TXT; manymouse/ carries its own license).
Version skew: the tarball is a mix of eras — device.c, ui/ are from
the 2014 v1.5d line; games/goldeneye.c, maindll.h, maindll.c are dated
2021–22; the bundle's binary is a 2023 build with a few later additions. The
aim model in games/goldeneye.c is stable across those versions and is the
one we already mirrored (finding D194). Consult it for the model and
constants, not as an exact match to any single release.
Key files
| File | What to look at |
|---|---|
games/goldeneye.c |
The whole GE input/aim model. GE_Inject() = hipfire direct camera write + tank + menu cursor; GE_AimMode() = crosshair-position aim (±5.159° limit, 72% edge threshold, 475/s scroll — the D194 source); GE_Crouch() = crouch-toggle state machine; GE_Controller() = button mapping (wheel→weapon macro, aim=B in menus); GE_InjectHacks() = ROM patches we do NOT port (reload key, FOV override) but which document intended behavior. |
games/perfectdark.c |
PD analogue of the same model (radial menu, hoverbike, camspy). |
device.c / manymouse/ |
Raw-driver mouse polling + cursor lock (SetCursorPos cadence), wheel cooldown handling, multi-device mapping. |
maindll.h |
TICKRATE/TIMESTEP (2 ms overclocked / 4 ms stock) — the units every per-tick constant in goldeneye.c assumes. |
global.h |
Settings enum (sensitivity range 1..80, acceleration, crosshair-movement %, invert pitch, crouch toggle, aim mode). |
vkey.h |
Default key layout (WASD=C-buttons, Q=A, E=B, R=reload, wheel=weapon cycle). |
