More geeky than most of us can handle, musician Herbert Weixelbaum has an in-depth analysis of the sound output for every Game Boy system, including both Nintendo DS models. He even included minor upgrades to the line and tested systems with backlighting both on and off. The guide is aimed squarely at chiptune musicians who want to get the most out of their performances. Everyone else, just smile and nod.
The results? The original Game Boy has a "warm, bassy sound", the Game Boy Color produces a lot of background noise, while the Game Boy Advance SP has the best display. According to Herbert, however, the original Game Boy is the best of the lot with the all-important "retro feel".
