you can hear it. what i mean is, it might be desirable not having it emulated because it means the triangle and noise channels don't get somewhat muffled when dpcm is used.
this is how I know it isn't emulated in GEP: 1, 2. trivol in GEP will be a steady tone. on other players, the volume of the triangle will audibly decrease. as for trivol2, in GEP you'll just hear a bunch of clicks getting faster, while in other players you'll hear the volume going up and down constantly.
nope, both pass. you'll hear clicks in any player, but in nezplug and most other players you'll also hear the volume fading/jumping respectively. GEP is the only player I can think of that fails and you'll only hear the clicks and not the volume attenuation.
understand?
EDIT: turns out nsften, nosefart and nintendulator have the same problem for anyone who uses those, though those are pretty bad in plenty of other ways as well. i've tried every other winamp plugin and standalone nsf player I can remember.
