## Input and aim

`port/src/input.c` maps **SDL2 keyboard, mouse and gamepad** events into the
N64's own controller structs, so the game's input code runs unmodified.

**Mouse aim** is modelled on the *GEPD* mouse-injector behaviour that the 1964
"GoldenEye/Perfect Dark Edition" bundle used — an **independent
reimplementation** of that behaviour (not derived code), credited to its
author in the README. It comes in two styles, the N64's own aim feel or a
centered FPS-style, with per-device sensitivity, smoothing and Y-inversion.

**Controllers:** modern pads get a dual-stick layout, deadzones,
sensitivity, southpaw, trigger thresholds, Rumble-Pak vibration, and
PlayStation/Nintendo button names. **Everything is rebindable** — keyboard,
mouse and each controller — in the F10 options overlay. Split-screen needs one
controller per extra player.

**Control style** offers **Ext** (this port's scheme) or **Original**, the
game's own N64 styles 1.1–2.4, chosen per seat. New profiles start with
**Look ahead** off (it fights mouse look) and **Crouch** on Toggle; the
game's own Look up/down row was removed in favour of **Invert look** on the
Mouse and Controller pages.

provenance is the D194 lineage in `port/src/input.c`.*
