[GB] Prehistorik Man seems to have Channels 1 and 2 muted

[CasualPokePlayer]

Tried on 0.9.3 and 519968d. Seems to sound identical to disabling Channels 1 and 2 in bgb.

Can you see if this worked in previous releases? I swear it worked at some point.

[CasualPokePlayer]

Tried 0.8.4, 0.7.3, 0.6.3, all bugged.

That's probably far enough back, though I suppose there's a chance it worked in 0.5.2. I won't treat it as a regression then.

This was definitely not a regression. This is really old code. I guess I just misremembered.
