In this tutorial I will show you how to under ore overclock a gameboy classic..
When you underclock a gameboy, it will run slower then usual, and when you overclock a gameboy it will run faster.
It is realy easy to do and fun!
p.s.1: my opnion: it will not enhance the quality of your music.. but just do it anyway (-:
p.s.2: Thanks to Kbud for providing me with info about clocking the gameboy.
p.s.3: The gameboy that surounds the page was made with the image to table converter.

STEP 4: Unsolder the clock from the other side of the circuitboard, and replace it with the new clock.
Clock speeds are.

  • 2.097152 (half speed)
  • 4.194304 (normal speed)
  • 6.291456 (1/3 faster)
  • 8.388608 (two times faster)
  • 12.582912 (crash speed don't try!!)

Some extra advice:

The clocks come in different sizes, so try to find a clock that has the same size as the one you got out of your gameboy.

People call "it changing the clock speed" of something.. But the clock you are changing is caled a Crystal-Oscillator, so if you are beying one call it Crystal-Oscillator and not clock.


STEP 5: Put the gameboy back together...
And now you are done (-:


If you want you can also put in a switch so you can switch between origonal or under/overclock mode..
