Desmume how to speed up

A Complete Guide On How To Make DeSmuME Speed Up 2022 Update

The DeSmuME emulator is designed for Wii, Windows, and Macintosh Nintendo. It can replicate several different Nintendo DS ROMS and demos.



The emulator is far from perfect and is still running, though it can simulate several ROMs. The DeSmuME emulator focuses more on game compatibility than speed, so there’s only as much you can do.

This is something that you should bear in mind when tuning the DeSmuMe emulator to increase speed.

Use DeSmuME products

You can find a wide range of tools on the DeSmuME’s website. It will make your job easy when you want to enhance the speed of your emulator, and they are of higher quality than others. Try to halt beyond unofficial SVN builds as they will only slow down your system.

Use the TAB key on your keyboard

This is not a legitimate way when it comes to improving the speed of DeSmuME Run Faster, but it is useful in some instances. Press the “TAB” when you observe that your DeSmuME is delaying during your games.

In a few devices, the identical result will come by pressing Spacebar. Try both of them and then find which one is appropriate for you.



Steps Simplified

Step 1

Enable “Patch DelayLoop SWI” if you have to use an external BIOS image. It is recommended not to use a BIOS image because it slows down the DeSmuME emulator.

Step 2

Press “A” on “Settings” and switch between OpenGL Renderer and Software Rasterizer. This may improve the speed of the emulator. Press “A” on “Config” and go to “Emulation Settings” and unclick the checkmark next to “Enable Bus-Level Timing.”

Step 3

Access the “Sound Settings” and check to use “Dual SPU.” Do not set the emulator to use “Advanced SPU Logic” and set “interpolation” to “none.” Turning the sound off altogether will increase the speed of the emulator.

Step 4

Use the DeSmuME builds that are available on the DeSmuMe website. Any other unoffocial “SVN” builds or the NOSSE2 build is not compatible and will be slow.

Step 5

Enable frame skip by going to “Tools” and clicking on “Frameskipping.” Enable frameskipping by “1.” This will make most games still be able to play. Go to “View,” “LCDs Layout” and “One LCD.” This will hide the second LCD.

This is useful if there is nothing being displayed on the second LCD screen, however it will not speed up the emulator speed. Do not use resize filters or scale the window to any other size than “1x.”

Step 6

Do not use a netbook because they do not have the power to run this emulator. If you are using a laptop or notebook computer, disable the power management.

This will allow the computer to run at a better speed. You may also consider purchasing a faster computer or increase your RAM speed by purchasing upgraded RAM cards.

It is also wise to install an upgraded CPU. Clean any dust that is blocking your computer fans to allow them to cool your computer better.
