This honestly has to be one of my favorite songs. My friend and I would be SO happy if somebody make sheet music for this.
I love arranging 8-bit music, however, I don't think I'd want to take this song on because I have no idea how I would do the begging.
This music isn't 8-bit though...
This game is for Gameboy Advance, which I believe is 32-bit.
Oh...
Nonetheless, it doesn't seem to use more then 3 voices.
You realize that there are plenty of songs on the radio today that use 3 voices, and they're most certainly not 8-bit. :P
Fine, let me rephrase that. I like arranging music with a small number of voices or songs where the voicing resembles counterpoint.
Happy?
Yes.
But seriously, check out how many sprites went into this one creature that appears in the game for only one scene. (http://www.spriters-resource.com/gameboy_advance/mother3/sheet/15727/)
