In RetroArch, when going to Settings > Video > Scaling and changing Custom Aspect Ratio Positioning, you hold your keyboard’s left / right arrow keys to increase or decrease the number, the only thing is, it is sp painfully slow. It takes upwards of five minutes if you want to dramatically alter the screen size for a handheld system, for example. Is there any way to increase the speed of this process, is there a keyboard key I can simultaneously hold down with the arrow keys to make this a faster process?
Thank you in advance.
