32X Init and Sound bugs

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open ROM "WWF Wrestlemania Arcade (32X) (W) [!].32x"
2. Try to play :)

What is the expected output? What do you see instead?
(1) In gens_11 you can play, but even in gens_11a - you can't play.
(2) Not all sounds played. (PWM not works?)

What version of the product are you using? On what operating system?
gens_11a, gens_11b

Please provide any additional information below.
(1) If you want fix it - just comment in gens.cpp line 1664. But, I think it's 
buggy. Check this line, or even whole branch.
(2) I see some strange effect. Every time when I trying to open 32X ROM - PWM = 
Disabled (even if Enabled before).
