Description

This is a feature request.

Add menu items (in glui etc.) to toggle slow motion and fast forward on/off.

Use case is on a phone with no physical controller, there is no way to do that. (Some on-screen overlays do have a fast forward button but most don't.)

Extreme slow motion would be useful to help determine the optimal number of run-ahead frames for each game.

Research direction

Start by locating the glui menu implementation, since the issue specifically calls for menu items there. Check how existing menu actions expose slow motion and fast forward, then add on/off controls and verify they work on a phone without a physical controller, including extreme slow motion for run-ahead tuning.
