AHK

AutoHotkey (AHK) is small but powerful automation scripting language for windows.

In this Quick video I demonstrate how to install AHK and create your first script. All AHK commands can be found here if you are creating your own scripts: https://www.autohotkey.com/docs/AutoHotkey.htm

This scripts helps change DPI and Resolution of your monitor in windows 10. Some games need the DPI to be 100% or the gun will not work

Lets talk through this script

• Line 6: this is the hotkey to change enable the change (currently set to ! (ALT) + # (WinKey) + PageDown. You don't have to use a key bind to call the script you can put in before your load your rom and then run the 2nd part in your exit script NOTE You need RegWrite before calling the change res.

• Line 7: "ACR0408#ASNmpEVZnard_00_07DD_A1^1977EFB0FCDDA00B4A190B2C0A4C2256" is the name of my monitor this will need to be changed to your monitor name This can be found here

The possible values for DPIValue are the following 0 = 100%, 1 = 125%, 2= 150%, 3= 175% and 4= 200%

• Line 8: this is for your Resolution settings
• Line 11 to 14 are the same as above You need to change these settings also
• Line 18 to 25: you don't need to change anything here. This just changes the settings and applies them. If this isn't here the regedit would not change anything

NOTE: If you have 2 or more monitors you will need to choose one under HKEY_CURRENT_USER\Control Panel\Desktop\PerMonitorSettings\ and do a trial and error. I don't know how windows makes this reg folder for the display name.
