This article shows how to mod your Nintendo DS Lite so that you can overclock it or underclock it any time you want, even in the middle of a game. It’s great for adjusting the difficulty level of your games or getting extra CPU cycles for homebrew apps. It’s a completely stealth installation, so you don’t have to go cutting any ugly holes in the outside of your DS case.
