Nice mod that you made for the Snes9x, I don't know if it's the first mod ever for the Snes9x or not but still pretty good.
One small problem is that while I was playing some ROMS from either SMW games or other SNES games is the audio.
I'm not sure if it's me, but while the music plays perfectly with good FPS, sometimes I hear random "crackly" noises but goes away in a second but after awhile it comes back and ends after the second.
I messed around with the audio settings and the new mod settings but nothing has worked to stop it.
Maybe because It's version 1.58? I'm using version 1.55 and it has perfectly clear audio with no crackly sounds at all.
