Metroid (NES/FDS) Audio Comparison

A full comparison video between the audio differences of Metroid on the Nintendo Entertainment System (NES) and Famicom Disk System.

NOTE: Both versions of the game were recorded from original hardware (an original front loading NES, and an AV modded Famicom equipped with the Famicom Disk System).
None of this is emulated.
