Ways to Make Your Emulator Work Efficiently


The article is all about Emulators and the ways in which you can make your emulator work more efficiently than before. This ultimate guide takes you through the process of configuring your emulator to the best of settings for a fun-filled and complete gaming experience.

What is an emulator?

We begin by explaining what an emulator is. In simple words, it is a program that allows you to run different software from different devices on your computer. It is custom-made hardware that is used to simulate another device. These emulators are used to play video games or to run other operating systems on the device. For example, an emulator can be used to run a Mac OS on a windows device. They are used to run applications that usually don’t work on a computer. In a technological world, it refers to the ability of a computer program to imitate another program, hence, making the program accessible and not exclusive.

Many video game enthusiasts use emulators to play classic or arcade games from the past, using their codes and data, making them run on a system of present times using an emulator. One such emulator is the DeSmuMe Emulator that is designed for the Nintendo DS. If you’re having issues with it, Make the DeSmuME Run Faster with this easy guide. We are sure our guide will help you in making your DeSmuME emulator run faster than ever. These emulators imitate the old video game consoles.

How do emulators work?

Different types of emulators use various emulation techniques. However, the end goal is always the same: to recreate the experience of using the original gear or program. Some emulators are more powerful than the actual product and come with extra capabilities.

Emulation necessitates a large amount of computing power. Emulators might take a long time to construct because unpaid programmers usually create them. Many fall behind their real-world counterparts in terms of performance as a result of this emulation penalty.

The whole process of emulators is closely related to the concept of virtualization. Virtual machines are emulators which run on the hardware of the host systems. As a result, no emulation tax is imposed on them, but they are limited to what original machines can do.

List of the most common emulators

These are commercial and open-source emulators which are present for all the major OS.

  • BlueStacks – Allowing Android apps to run on Windows and Mac.
  • Xcode – Enables IOS to run Mac and Windows.
  • WINE – Enables Windows to function on Linux OS.
  • Nestopia – Allows Nintendo games on Linux OS.
  • Appetize.io – An emulator that allows the use of IOS apps on any PC.

Thanks to a multitude of emulators, users may play games from other platforms on the PlayStation Portable.

Console emulators such as the SNES classic are separate hardware devices that allow gamers to play old games on modern televisions.

Ways to make emulators work efficiently

One of the most powerful tools in the Android developer’s armory is the emulator. It allows you to test your Android projects on a much larger number of devices than you could ever expect to get your hands on.

However, the emulator has one major issue that becomes apparent the first time you use it. Make yourself at home because the emulator takes a long time to load. But there are different ways in which you can use the emulators to run faster and more efficiently.

  • Checking system specifications properly: 

Emulators are powerful engines requiring very high-quality specifications and even higher capacities to run smoothly. If you want emulators to run at full speed on your PC, you’ll need top-of-the-line components like the best processor, GPU, ROM, RAM, and so on. Systems with Windows 10 (64-bit), advanced AMD or Intel processor (octa-core), 8 GB RAM, and proper GPU setup will make the emulators run smoothly.

Similarly, you can also reduce the resolution of the emulator to get better performance.

  • Reduction in resolution: 

Usually, if the system’s resolution is higher, it means that more hardware power is needed, and hence the emulators work slowly. Consequently, a reduction in the resolution leads to a direct impact on the efficiency of the emulator.

Here’s a small guide to reducing resolution :

  • Select Plugin/BIOS Selector from the configuration menu.
  • Click the Configure icon next to the GS dropdown menu on the Plugin tab.
  • Reduce the resolution by following the on-screen directions.
  • Restart your computer.

After that, your emulators should run more quickly.

  • Enhancing GPU and its performance: 

As mentioned earlier, To improve the efficiency of the emulator, it is very important to have a high-quality GPU. Hence, you can improve the quality of the emulator by enhancing the graphic cards and their performance. These are the following steps:


  • Right-click on the desktop
  • Select NVIDIA control panel
  • Select manage 3D settings.
  • Choose Global Settings
  • Under the Preferred graphics processor dropdown option, select High-performance NVIDIA CPU.


  • Click the Start button on your desktop.
  • Programs should be chosen.
  • Select Catalyst Control Center from the Programs menu and click it.
  • Select Power from the dropdown menu.
  • Choose Switchable Graphics Application Settings.
  • Find the emulators on your computer.
  • Set each emulator’s performance to High.
  • Restart your computer.
  • Free up memory

If the system is full of redundant apps, it will directly affect the system’s performance and, hence, reduce the emulator’s efficiency. This is exacerbated if you have numerous high-powered apps or processes operating at the same time. As a result, you may need to free up some memory on your machine to make your emulators run faster in this instance. The only way to accomplish this is to “kill” or disable some currently active apps/processes. In extreme cases, sometimes high-performance apps have to be uninstalled to create space for emulators to work.

The user may use several other notable modifications, hacks, and solutions to increase the speed with which emulators run on PCs. Enabling VT (Virtual Technology) in BIOS and deactivating the debug window are two examples.

In any case, if the tips mentioned above are properly executed, all emulators on your PC will operate faster.
