MG330 Studio: reconstructing SPCP6651B mouse configuration

MG330 Studio recreates configuration control for the 2E Gaming MG330 RGB mouse on macOS using the SPCP6651B HID feature-report protocol recovered from its Windows driver. It reads and writes the device's 2 KB configuration, covering RGB zones, DPI, polling rate and effect slots; protocol notes map report IDs, offsets and checksums.

Requirements & limits

Prerequisites: macOS 14 or later, a Sunplus SPCP6651B mouse and Input Monitoring permission; tested on the 2E MG330 RGB.
Prerequisites: Xcode 16 is required to build; a stable code-signing identity retains the Input Monitoring grant across builds.
Limits: Button remapping is read-only; effects 2–7 were accepted by firmware but their appearance was not checked.
