Universal Joystick Driver

Legacy Game Port devices cannot be hot-swapped; they require static I/O port and IRQ assignments. A universal driver on modern systems must include legacy support modules that fall back gracefully or emulate Game Port over USB adapters.

The driver uses a StandardState struct to represent the controller state at any given frame. universal joystick driver

Without a universal driver, developers would need to write separate low-level I/O handlers for each device. This is impractical for end-users and software vendors. A universal driver abstracts these differences, presenting a consistent virtual interface (e.g., a normalized axis range of 0–65535 and a linear array of button states) to user applications.
