You know there are lots of different Game Boy models, of course. But do you know how their sound output varies over the multiple different DS and Game Boy SKUs? Chiptune musician Herbert Weixelbaum does, and he's created a massive, newly updated page profiling the different noises each GB makes.

He explains of this pretty cool analysis: "not only do the different game boy models sound different, if you have a look at the waveforms, you can see, that these already look very different (thin sound - thin waveform). i recorded the pulse instrument, envelope: A8, wave: pulse width 50% (square), with a pitch of C3 (which is great C, in musical terms)."

Weixelbaum's conclusion? "things like "retro feel" might or might not be of importance to you, but it is a pretty objective judgment, that the original game boy (or the original with the pro sound mod) has the best sound, while the game boy advance sp2 has the best display. if you want to use a gba program, like nanoloop 2.0, the ds lite has the best sound and display."
