GBAccelerator GBA



Mod allows you to change the speed of your Game Boy Advance, Game Boy Advance SP, or Game Boy Micro at the press of a button.

SKU: XLCOMP01 Category:


This mod allows you to change the clock speed / game speed of the GBA to one of four speeds, including normal, fast, ultra and slow-motion using the GBA’s own buttons. GBAccelerator is useful for quickly bypassing text in games, speeding up games when they experience ‘slowdown’, for slowing down the action in tough games and for custom homemade games made to use the faster processing power that GBAccelerator provides. Chiptune producers will be able to create new, crazy sounds since the audio changes pitch as the speed changes.

Unlike crystal switch mods, changing speeds with GBAccelerator does not cause clock glitches.

This kit features completely internal installation so it won’t affect the look of your Game Boy.

Note: Basic soldering skills are required to install this mod.


GBAccelerator GBA will work in the following handhelds:

  • Game Boy Advance
  • Game Boy Advance SP
  • Game Boy Micro

If you’re looking to overclock a different Nintendo handheld, check out GBAccelerator GB, GBAccelerator GBC, or GBAccelerator DS.

*Note: This mod is only guaranteed to work with a stock Game Boy Advance.  Any other mods that have been done to the GBA, including upgraded screens, may or may not work with GBAccelerator.  GBAccelerator will overclock your system; it’s up to those other mods as to whether or not they will work when overclocked and the GBAccelerator has no control over that.
