Nintendo NES Overclocking Guide

Posted by timothy on from the what-everyone's-been-waiting-for dept.

Deven "Epicenter" Gallo writes "I've perfected a process by which to overclock the Nintendo Entertainment System (NES) to run games smoother without slowdown. The NES CPU normally runs at 1.79 MHz, I've reached a stable maximum of 4.2 MHz, about a 230% overclock. The games do not run faster than they should, the CPU never overheats, and most games are perfect up to 3.3 MHz!" Here's the guide on how to perform the modification, along with photos and demonstration videos

    I tested about 10 games out (some of which I listed info about on the site). I don't have any that refuse to run-- every one handles at least 3.0 MHz. The pitch increase isn't as bad as theory would suggest it should be. In fact, it seems to kind of improve the tone of audio in some games, and a lot of the time, 'out of key' audio is put back IN key (most notably Metroid). That's my 2 cents. Sticklers for 100% perfect original audio won't be thrilled I'm sure. But I'm damn finicky and it still doesn't bug me.
