Hey guys, so I made an backup of my totally legit copy of MGS 1 from Playstation 1, and booted on to play on adrenaline, but then I noticed some audio bugs, I tested other ps1 games, and the audio are just fine, the problem is the MGS Port to PSP.
The audio keeps repeating and overlaping. I searched and found out that its a problem of the PSP port of MSG, as you can see here.
So my question is, is there another way to play MGS 1 on psp or ps vita? If not, is there some patch to this version of the game?
