So I'm playing Yakuza 1 with mouse and keyboard (bad idea, I know) and I'm stuck on the funeral part where you have to sneak by walking. So, I've been looking for instructions on how to change analog pressure with a keybind.

For example, when I press W normally my character runs forward with full speed, but if I press W + alt (or any other button) the game only receives 50% analog output, so my character walks instead. I'm going insane looking for a tutorial about this, does anyone have an idea? Please, anything would be appreciated.
