Well. Apparently FPSE is not working correctly with the sound settings. After I ripped off the image from the game, I tried to open it up with FPSE, the boot went nicely and the video was working with almost no glitches. But somehow the sound was not working properly. The link below shows what happens:
-WARNING! EXTREMELY loud gltichy sound, do not use high volume!!!

Metal Gear Solid does not start the sound at all... Not even the boot sound happens.
As a matter of fact, the ROM I use is not glitched. The ePSXe emulator from retroarch is not glitches at all. 100% Working correctly!
What can I do to fix the problem?
