Android Emulator - How can I keep all instances (windows) focused at the same time?

[Tejahn]

Fair greetings! I'm very new here but I've been researching and trying to find a working code for days.

Here is my dilemma. I'm currently using MeMu to reroll an account but the process has become tedious. So, I decided to open up 4 instances and reroll 4 accounts at a time. The problem is that the unfocused windows lag. I need a script to keep all windows focused at the same time so each instance of the game will run smoothly. Can someone provide a working code?

As far as I am aware, only one window can have the focus at any one time.
