Are you sick of wasting time playing long games like pokemon? In this giude you can overclock your GBC to play all games at much higher speeds so that you don't spend hours trying to beat your favorite games. On a side note, this is my first instructable. Yay!
Since I have done this instructable, I have made diagrams on how to use a socket to switch out crystals and how to use a switch to change speeds. Those diagrams can be found here http://forums.modretro.com/viewtopic.php?f=40&t=114
