 - **GlobalInputs** (`global_inputs.hpp/cpp`) — Maps configurable function keys to presentation actions. Uses debounce. Returns whether a key was consumed (to suppress from game layer)
 - **Mouse** (`mouse.hpp/cpp`) — Auto-hides cursor after 3 seconds of inactivity
-- **Gamepad** (`gamepad.hpp/cpp`) — First-gamepad support with hot-plug. Poll-based each frame: D-pad/left stick (deadzone 12000) → virtual arrow keys for game movement; A/B buttons, Start, Back translate to synthetic SDL key events (F12/ESC/Enter/Backspace) when menu is open, so Director handles them exactly like keyboard

Loads extra mappings from `gamecontrollerdb.txt` (next to the executable) at init via `SDL_AddGamepadMappingsFromFile`, extending SDL's built-in controller database
 - **KeyRemap** (`key_remap.hpp/cpp`) — Each frame, reads `Options::keys_game.*` and mirrors physical keyboard state to virtual standard scancodes (`SDL_SCANCODE_UP`/DOWN/LEFT/RIGHT). Allows full movement key remapping without touching hardcoded game code in `prota.cpp`/`mapa.cpp`
