Cool easter egg/glitch in VirtuaNES

[_oMeGa_]

I found this wierd glitch in VirtuaNES, Alot of times, I like playing games to music, so i tried playing punch out with no sound but my own music, when i changed to full screen, VirtuaNES added a sort of... filter, and made my music sound like NES music!
I just felt like sharing this cool glitch, heres what to do if you wanna try.
1. Go to options, sound, and uncheck enable sound
2. Start some music, start a game, and go into fullscreen.

What version of V-NES are you using? Also, what types of music are you using (MIDI, MP3?) and what are you playing them in? O.o

It would help to know.

I'm using version 0.92, I use windows media player, and they're mp3s.
