The official driver is bloated and hides the mouse's most useful switches. This tool exposes everything stored in the mouse's onboard memory, plus a wake-on-move feature the official driver never offered:
- Wake on move — when idle the mouse throttles down to save power, and any input instantly restores your polling rate. No more waking a sleeping mouse with a click that accidentally registers.
- DPI: 1–6 stages (1/2/3/6, cleanly divides the firmware's fixed 6-slot cycle), per-stage DPI, active stage
- Polling rate: 125 / 250 / 500 / 1000 Hz
- E-sports mode, lift-off distance, button debounce
- Battery level, firmware version, config export/import, factory reset
- Light / dark / follow-system theme; Traditional Chinese / English / Simplified Chinese
Settings are written to the mouse itself, so they persist across computers and connection modes.
Download the single .exe from Releases, double-click it — no installation. Connect the mouse via USB cable or the 2.4G dongle (Bluetooth mode cannot be configured), click Connect, adjust, then Apply.
Turning on Wake on move also enables "minimize to tray on close" so the background power-saving keeps running.
The protocol was reverse-engineered from darkFlash's own web driver. The app is a thin C# shell hosting a local page over WebView2 (so WebHID works); "wake on move" is done in the background by monitoring system idle time and adjusting the mouse's polling rate. Full protocol notes are in PROTOCOL.md.

官方驅動又肥又把最實用的開關藏起來。本工具把存在滑鼠機身記憶體裡的設定全部開放，還多做了一個官方沒有的移動喚醒：
- 移動喚醒 — 閒置時滑鼠自動降頻省電，一有操作立即恢復你的輪詢率。再也不用「點一下」叫醒睡著的滑鼠、也不會被那一下點擊誤觸。
- DPI：1～6 檔位（開放 1/2/3/6，能整除韌體固定的 6 格循環）、各檔 DPI、目前檔位
- 輪詢率：125 / 250 / 500 / 1000 Hz
- 電競模式、LOD 靜默高度、按鍵去抖動
- 電量、韌體版本、設定匯出／匯入、還原原廠
- 亮／深／跟隨系統主題；繁中／English／簡中
設定寫入滑鼠本體，換電腦、換連線模式都持續生效。
從 Releases 下載單一 .exe，雙擊即用、免安裝。以 USB 線或 2.4G 接收器連接滑鼠（藍牙模式無法設定），按「連接滑鼠」選擇裝置，調整後按「套用」。
開啟「移動喚醒」時會一併開啟「關閉時最小化到系統匣」，讓背景省電持續運作。
協定逆向自 darkFlash 官方網頁驅動。本程式是一層輕量 C# 殼，用 WebView2 載入本機頁面（讓 WebHID 可用）；「移動喚醒」由背景監測系統閒置時間、調整滑鼠輪詢率達成。完整協定筆記見 PROTOCOL.md。
