This is a fake.
First, all the 'PSIN' files are renamed VB executables.
Second, they want you to replace dll's in your System directory.
Third, notice that the first four letters of "efakemulator" make the word "fake" backwards.
Fourth, the instructions tell you that the file that you load has to be in "PS2" format, whatever that is supposed to be...
This is most likely a vandalism app that fux up your machine.
Good luck!!!
