I kept getting asked to do a sidebyside, comparison so here it is: Analogue Pocket x Prosound DMG (with backlight installed) synced via Gameboy link cable, playing the same song in LSDJ while using the Dirtywave M8 as an audio interface into my computer.

In my opinion they sound incredibly close. There's a small difference in noise/freq range clarity as you might expect when dealing with brand new hardware vs 30 year old tech, but it's no different that the difference you would expect when comparing two different models of actual Gameboys, or even the same model Gameboy with different CPU revisions.

Analogue did a helluva job with the accuracy on this. It gets my official seal of approval!
