How to Set Turbo in v2.1.4

I have made it that this post may function as stand-alone outside the introductory topic. Feel free to move somewhere else if you decided to have a quick guide section.

How to modify Speed Throttle setting (otherwise called Turbo Mode)

I am using the VBA-M version from here ->

First thing that I noticed is that VBA-M gets pretty confused if you've changed one setting too many so it is good to firstly reset the Emulator to its default settings.

  1. Go to Help -> Factory Reset

    This will remove all your previous settings (and all your previous attempts at fixing the speed issue :)).

  2. Restart the emulator.

  3. Load a ROM (I am using Pokemon Leaf Green)

  4. Now you should be able to run the game in Turbo mode (1000% of normal gameplay)

  5. Go to OPTIONS -> VIDEO -> and enable the status bar to see the the game's speed in the right bottom corner of the screen.

  6. Press TAB or go to EMULATION -> Turbo Mode to turn on the Turbo mode.

However you may want to slow the turbo mode down a bit (just like me). To do this you need to modify one setting. But before that a safety warning.


Don't change any setting that has % and throttle mentioned in its name:

  • "Speed Up Throttle" from OPTIONS -> Speed Up - Turbo mode

  • "Throttle % of normal from OPTIONS -> General

In order to modify the speed of Turbo Mode all you need to do is to modify the "Speedup Frame Skip field"


  • "Speedup Frame Skip field" from OPTIONS -> Speed Up - Turbo mode

By default this field has the value "9" which means that the game will run at 1000% speed. I have it set up to 3 which gives Turbo mode at 400%.

Your set up should look similarly as my (see below). Don't touch anything that is marked in red :).

Thanks for posting this. This is exactly was I was looking for after having some issues with the turbo mode settings (I was changing the "Speedup Throttle" setting). However, I still can't get it to work correctly. I followed the steps you outline and set the "Speedup Frame Skip" to 2, but when I turn turbo mode on, it jumps to 1000% speedup. I had mixed results with "Speedup Throttle", so I might experiment with that a little more. Any thoughts about what I might be doing wrong?
