I'm a bit new haha. And I've made this so far; it's Atop the World; the main track to Tower of Heaven. And in the original, which is an 8bit itself, it has a lower, more rougher sounding bass tone that compliments the lead... Or something along those lines hahaha. I am just confused on how to get this more rougher tone than what I am using right now.
The original is: http://www.youtube.com/watch?v=dec4Qgoi4TQ
The original is supposed to sound more like a Gameboy, that's why. Gameboy has a custom waveform instead of a triangle wave like the NES. Also, the original isn't true 8-bit as far as I know. Either way, if you want a beefy bass, play with the FDS channel.
