I don't see how that patch would lead to piracy. VGS works with backups whether it's patched or not, but sometimes it spits out discs it doesn't like, more often than not backup discs. I've tried using VGS with and without the Morlac patch, and the only thing i've noticed is that sometimes the unpatched .exe doesn't read some backups, and sometimes even my original japanese import games!
So basically what that patch does is to force VGS to read whatever disc's in there regardless of whether it's a backup or the original.
