GBAccelerator DS Operating Instructions

When you first power on your Nintendo DS, it will be running at normal speed. At any time during gameplay you may change the clock speed by simultaneously pressing L, R and Select (or whichever combination of 3 buttons you connected the GBAccelerator DS to). The power LED will indicate which speed is currently selected. The following table shows the available speeds and their corresponding LED codes:
