The old GB sounds were harsher and I am going to speculate it's because the SNES has a heavy low pass filter that smooths out things maybe a tad too much. The GB metroid sounds I feel like I can sit and remake them with square/sawtooth waves (both waves have sharp corners!) and some creativity. The SNES sounds sound like samples + DSP. Metroid 2's world felt very alien, hostile and unforgiving to me as a kid. The complete black background and lack of dense enemies drove the point home that the metroids literally ate everything!
