Homebrew Question Retroarch: FastForward and fullscreen toggle doesn't work

[Keylogger]

Hey

I am playing some GB/GBA and NES roms with retroarch
I have configured fast forward and fullscreen toggles in "Input", "Input Hotkey binds"

But in game, toggles don't work..; "Fast forward" is displayed in left bottom screen but the game is running at same speed and fullscreen toggle doesn't work at all

What is the problem.?

You need to turn on Threaded Video in the Video Settings

You need to set the Aspect Ratio to 16:9 and Integer Scale to OFF
