LuminalShine 26.07.0-beta.3

An incremental beta on top of 26.07.0-beta.2, focused on keeping the host's Steam overlay reachable from clients that cannot send a Guide button press.

General

• No changes in this release.

Windows 11

• New: Home/Guide Button Combo (Settings → Input). Emulate a Home/Guide button press on the virtual controller by holding a chosen button combination on the streamed gamepad — opening the host's Steam overlay from clients that cannot forward a real Guide press. On a Steam Deck running MoonDeck, the Steam button is consumed locally by the Deck, which previously left the host's Steam overlay unreachable mid-session (no accepting game invites, no switching to a friend's lobby). Available combinations:

  • Start (Menu) + Back (View)
  • Back (View) + X, Back (View) + Y
  • D-Pad Right + X, D-Pad Left + Y
  • LB + RB + Start — three buttons, the hardest to trigger accidentally

  The feature is off by default, triggers once per press with a one-second debounce, works on both classic Moonlight and WebRTC sessions, and can be scoped per application via Setting Overrides (e.g. only your MoonDeck entry). Note: the combo buttons still reach the game in the moment before the overlay opens, so pick a combination your game doesn't use.
