Remote osu! Keyboardの旧いバージョンをダウンロードすることが可能
リモートOSUを使用してください！ OSUのキーボードなどのキーボード！ゲームプレー
Use Remote osu! Keyboard as a keyboard for Standard osu!, Mania and Taiko gameplay. This makes playing silent, streaming easier and removes any need for an expensive keyboard.
Before you can start using it, you have to download a server to your computer. You can do so on this forum thread: https://osu.ppy.sh/forum/t/391981.
All you need is a wifi connection. It doesn't have to be fast, because Remote osu! Keyboard sends as little data as possible across the network.
