good music and the graphics were good to for a system that was only about 2 mhz and usally had music that did not come close to this except for a few games.but i wonder how did the music composer make such good music.i wish i knew how.. i listen to it still in 2004,i think it sounds really good.

Yep, the music rocks!
They made the music in a kind of different way. From Wikipedia:
"Recorded bass tones were coded as DPCM-samples that added depth to the usual square and triangle waves by layering."
