PROBLEM 1:
First, I'm getting a lot of crackling on the triangle channel. I've read that it can happen but what causes it and how do I fix it?
PROBLEM 2:
Second, I can't seem to get the noise channel to produce any noise at all. Here's what I've done:
I've enabled the channel by the following write:
LDA #%00001111
STA $4015
...then I set the volume to F, disabled the saw envelope, and disabled the length counter with the following write:
LDA #%00111111
STA $400C
...then I set the mode to 0 and the tone to F with the following write:
LDA #%00001111
STA $400E
Still no sound from the noise channel. I checked the FCEUX 2.2.2 emulator's sound properties and the noise channel should be on. What am I doing wrong?
